Mycopunk Known Issues: Bug Fixes, Balance & 1.0 Roadmap

Stay on top of Mycopunk known issues — active bugs, recent balance changes, and where the 1.0 roadmap stands after each hotfix.

Mycopunk left Early Access on 2026-10-20 after roughly fifteen months in beta, and the 1.0 launch day shipped with a public Known Issues list that the developer Pigeons at Play is actively patching. This page is the running tracker for those Mycopunk known issues, covering the unfixed bugs at launch, the balance changes that arrived alongside the 1.0 update, and the parts of the post-launch roadmap the studio has already confirmed. If you bounced into X11-B on day one and ran into a broken Fulfillment or a missing cape, the answers below are built from the developer's own posts and the official store page, not third-party guesswork.

The launch window matters here: Mycopunk hit 1.0 on October 20, 2026, so community wikis and third-party guides are essentially empty. Treat this article as a snapshot of what the developer has published, with explicit notes wherever a number, upgrade, or feature has not been announced. The list will grow as the studio rolls out the 1.1 and 1.2 patches already teased on the roadmap, so bookmark it and check back after each Mycopunk patch notes update.

Active Bugs Reported in the 1.0 Known Issues List

The developer published a Known Issues list on the Steam page at 1.0 launch, and four items from that list were still unpatched as of the October 21, 2026 snapshot. Pigeons at Play has marked each one for the next hotfix, but none of the fixes are live yet, so players should expect to keep running into them during the first week of the 1.0 release.

BugAffected SystemStatus (as of 2026-10-21)Workaround

Rescue bags of Saxitos Fulfillment not progressingFulfillmentsUnpatchedFulfillment tracker stays at 0/3
Mycologist cape missing from the HUB modelEmployee cosmeticsUnpatchedCape renders as a placeholder mesh
Bunker Buster threshold bugMission scoringUnpatchedScore does not credit at the intended kill count

Three of these bugs are cosmetic or progress-only, but the Bunker Buster threshold bug and the Cranius achievement bug both block rewards, which is why most player reports flag them. Until the first hotfix lands, the Fulfillments system effectively has two thirds of its launch checklist locked, and players chasing 100% achievement completion cannot close the gap. The studio has not published a fix date for any of these five bugs, so players planning a completionist run should keep expectations in check.

The activate relay towers and rescue bags of Saxitos lines are the two Fulfillments explicitly called out in the Known Issues post. As of this writing, the developer has not published the full Fulfillment list, so any other launch-day Fulfillment could also be silently broken. If you are tracking Hats, plan around the published two and wait for the first post-launch patch before chasing the rest.

Balance Changes Bundled Into the 1.0 Update

The 1.0 update is not just a content drop. Several weapons, grenades, and one ammo type were renamed, and a handful of combat values were rebalanced to compensate for the new X11-B region and the Diffraction Driver ion scattergun. The full diff appears in the Mycopunk patch notes hub, but the balance changes that players are most likely to notice in their first few missions are listed below.

ItemChange at 1.0Why It Matters
Acid GrenadeRenamed to Caustic GrenadeOld guides still reference the Acid name; loadouts will not find it
Shock GrenadeRenamed to Voltaic GrenadeSame problem as above; old loadout presets need a swap
Explosive Bullets (Accelerator)Renamed to Combustive RoundsUpgrade names that referenced the old wording no longer match
MycologistAdded as the fifth playable employeeUnlocks via the Expedition Alpha rescue mission
Diffraction DriverNew ion scattergun, short-range cone by defaultUnlocks at employee level 10
Snowball GrenadeNew cryo grenade, unlocked from X11-BOne upgrade lets you roll it down a hill for cartoon-style growth
Population ControlNew mission type, added at 1.0Bounty-style clear mission with scaled enemy density
The CouchNew mini special assignmentShort side mission, lower difficulty than the main map set
FulfillmentsNew achievement/cosmetic systemRewards Hats; two launch Fulfillments are not progressing (see above)

The renaming pass is the easiest balance change to miss. If you load a saved build that referenced the old names, the slot will read as empty until you swap to the new wording. The Accelerator rename is especially important because the official upgrade list calls the new ammo type Combustive Rounds, and a build optimizer that still searches for the old phrase will not find anything.

For combat tuning, the developer has not published a per-weapon delta. What has been published is the Diffraction Driver default behavior: short-range cone on primary fire, with alt-fire spinning up a halo to tighten the cone and extend range. The studio has not released upgrade names for the new scattergun, so any specific buff numbers in a community guide are speculative. Treat third-party upgrade lists for the Diffraction Driver and the Snowball Grenade as unverified until the first post-launch patch ships a Codex update.

What's Confirmed for the 1.0 Roadmap

The 1.0 roadmap is the first thing players should read before chasing completionist content, because it tells you which features are guaranteed, which are still in planning, and which have been pushed out. Pigeons at Play published the roadmap in two parts: a near-term 1.1 patch already in QA, and a longer-term 1.2 feature drop. Numbers like room counts, enemy rosters, and the full Fulfillment list have not been published, and the developer has been explicit that those details will arrive with each patch rather than up front.

Roadmap SlotTarget PatchStatusConfirmed Details
Mycologist balance pass1.1In QAThe 5th employee's upgrade tree, damage values, and cooldowns have NOT been published
Bug fix sweep (Known Issues list)1.1In QAThe five launch bugs above are the priority targets
Backlog tiered reward program1.2ConfirmedTiered reward structure; final tier list has not been published
Fulfillment list expansion1.1 or 1.2Confirmed but date unclearNew Hats, additional tracking objectives
HUB rework polish1.1In QAThe 1.0 HUB rework shipped; polish layer follows
Additional Codex entries1.1ConfirmedThe 1.0 Codex inventory tab will be backfilled with new weapons and regions

Two roadmap items deserve a closer look. The Mycologist balance pass is the one most likely to land in the next hotfix, because the 5th employee only just became playable and the studio has openly said her upgrade tree, ability damage, and tier scaling are still being tuned. Until those numbers ship, the only verified Mycologist facts are her three names: Sporelift, Fungal Skewer, and the passive Infection. Any community guide that lists a fourth ability, a specific cooldown, or a damage percentage for the Mycologist is filling in blanks the developer has not authorized.

The Backlog tiered reward program is the bigger content drop, slotted for 1.2. It is a long-term reward track that runs in parallel with the Fulfillments system, so players who finish the 1.0 launch Fulfillments will have a second completion target waiting in 1.2. The tier list itself has not been published, so right now the only thing to plan around is that the program exists, runs alongside the HUB's existing progression, and will not ship in 1.0 or 1.1.

How to Report a New Bug and What the Dev Team Has Said

Pigeons at Play uses three official channels for bug reports: the Steam discussions, the official Discord, and direct posts on the developer's X account. Each channel has a different purpose, and posting in the right one speeds up the triage. The dev team has said in the 1.0 Known Issues post that the fastest path to a fix is a Steam discussion with a save file attached, because it lets the QA team reproduce the issue locally.

ChannelBest ForAverage Response
Steam DiscussionsReproducible bugs with a save file1 to 3 days during launch week
Discord #bug-reportsVisual or animation glitchesSame-day, but no formal tracking
X / Twitter DMsAccount or purchase issuesNot a primary bug channel
Official email (via store page)Legal or refund queries2 to 5 business days

The dev team has also committed to a Known Issues refresh on the Steam page every Friday during the launch window. That post is the single best place to confirm whether a bug you found is already on the list, has been fixed in a hotfix, or has been triaged into the next patch. The community has been told to expect two more hotfixes before the 1.1 content patch lands, so the refresh cadence should hold at least through the first two weeks of November 2026.

If you hit a bug that is not on the public list, the most useful single thing to attach is your Armament License ID and a clip of the reproduction. The license ID is the developer-facing tag for your save file, and it lets the QA team match your report to the exact build. Pigeons at Play have used it in past patches to track down edge-case bugs that did not show up in internal QA, so the extra 30 seconds of copy-paste tends to pay off.

Performance, Servers, and Other Open Items at 1.0

The 1.0 launch also widened the platform footprint: Mycopunk now ships on PlayStation 5 in addition to Windows PC on Steam, and both versions launched simultaneously. The dev team's posts have flagged two performance issues that the 1.0 Known Issues list does not fully cover: occasional audio dropout in four-player co-op, and a frame-pacing hitch when entering the X11-B moon region for the first time. Neither is on the official bug list yet, but both have been acknowledged in Discord threads.

IssuePlatformSeverityStatus
Audio dropout in 4-player co-opPC and PS5LowAcknowledged, not on the official list yet

PS5 DualSense haptics not triggering for the Swarm LauncherPS5LowTracked under the broader haptics pass
Steam overlay clipping the Codex tabPCCosmeticUnpatched, low priority

X11-B is the 1.0 high-difficulty region and a moon of New Atlas, and the electromagnetic storms there disable abilities on a periodic timer. The studio has not published room counts, enemy lists, or weather cycle durations for X11-B, so any community walkthrough that quotes specific room numbers is filling in gaps. The verified facts are: it is harder than the other launch regions, the storms shut down abilities, and it is the only place the Snowball Grenade can be unlocked.

On the server side, peak concurrent players at launch were around 1,839 according to the public Steam snapshot, with 4,825 reviews sitting at 86% positive for a Very Positive rating. Those numbers are a useful baseline for judging whether future drops are moving the needle, and they line up with the early-access audience the game built over fifteen months. The dev team has not published server capacity targets, but the launch peak was well within the engineering budget the studio disclosed in the 1.0 announcement.

Frequently Asked Questions

Where can I find the official Mycopunk known issues list?

The official Known Issues list is pinned to the Steam Community hub for Mycopunk and is refreshed roughly every Friday during the launch window. The list covers the five unpatched bugs above plus any newly triaged reports from the prior week, so it is the single best place to confirm whether a bug you hit is already on the developer's radar.

Will the unfixed 1.0 bugs roll into a save file and block 100% completion?

Yes for the Fulfillments and the Cranius achievement, no for the Mycologist cape. The two broken Fulfillments and the Cranius achievement will not retroactively credit when the fix ships, so affected players will need to redo the relevant objective after the patch. The cape is a cosmetic-only fix and will apply to existing saves automatically.

Has the developer confirmed the post-launch 1.1 and 1.2 patches?

Pigeons at Play has confirmed that 1.1 is in QA and that 1.2 will introduce the Backlog tiered reward program. Specific dates have not been published, and the 1.1 patch is expected first because it carries the bug fix sweep and the Mycologist balance pass.

Are the old grenade names (Acid and Shock) still in the game?

No. The grenades were renamed at 1.0 to Caustic Grenade and Voltaic Grenade, and the old names no longer appear in the Codex, loadout screen, or upgrade descriptions. If an old guide still references the old names, the wording is out of date, and the in-game items have to be searched by their new labels.

Does Mycopunk have a public bug tracker or Trello board?

No, the developer does not maintain a public tracker. The Steam Community Known Issues post is the closest equivalent, and the dev team has said they prefer a single pinned thread over a Trello-style board so that triage stays in one place. Players who want a per-bug status can read each Friday's refresh and check off the items as they ship.
