News / Patches / Hotfixes
This page tracks the public post-launch fix history for MOUSE: P.I. For Hire: hotfix dates, Steam build IDs, console rollout notes, trophy-related fixes, and the current shape of known issue cleanup. Where the public record is incomplete, the wording stays narrow and honest.
Latest Public Hotfix
The newest public hotfix we verified is v1.0.6, posted on April 25, 2026 for Steam build 22923861.
Launch Week Pace
We verified v1.0.1, v1.0.3, v1.0.4, v1.0.5, and v1.0.6 in the launch window.
Platform Rollout
The checked public notes consistently show Steam first, with PlayStation 5 and Xbox Series X|S often following on a separate rollout schedule.
Trophy Angle
Official hotfix notes explicitly addressed clue-collection problems tied to Our Lesser Brothers and Secrets of the Shrew Shortage.
Status Read
The launch-week pattern is pretty clear: the game shipped on April 16, 2026, then entered a rapid hotfix phase with multiple public updates in just over a week. The facts are strongest on Steam build timing, hotfix content, and select PlayStation 5 / Xbox version numbers. They are weaker on full platform parity reporting, especially where the public notes stop short of spelling out every Nintendo Switch 2 build.
For players, that means this page works best as a verification layer. If you are troubleshooting a trophy, a blocked quest, a clue that did not register, or a mismatch between Steam and console behavior, this is where the official fix trail starts.
It also matters for route planning. The Platinum Guide, Walkthrough Hub, and Advanced Tips all become more trustworthy when their bug warnings are read through the latest hotfix state instead of frozen at launch-day panic.
That includes late-run cutoff advice. If you are using the Jack Squat Cutoff Guide to protect side jobs, Baseball Cards, or P.I. Office cleanup, this patch page is the right place to verify whether a newer hotfix changed hub lockout behavior, replay assumptions, or other route-sensitive safety rules.
If you are checking whether an older article, sponsored placement, or monetized module still reflects the live game state, this page also pairs naturally with the About, Privacy Policy, and Ad Disclosure pages.
Why This Page Exists
A route warning from April 16 can still be useful on April 28, but only if we know whether it survived five public hotfixes. That is the whole point of this page.
Patch Timeline
These entries are restricted to fixes we could ground in checked public notes, build records, or current platform-version reporting.
The newest official hotfix in the checked record fixes a quest object that could stay stuck in a carry state, improves background-process cleanup when the game closes, and adds a Privacy Policy button to the title screen. The same official note says PlayStation 5 and Xbox Series X|S rollout is planned for the week beginning April 27, 2026.
Public patch summaries for v1.0.5 center on stability and progression cleanup: black-screen hangs, saved FPS settings between sessions, Tinsel Ave issues, Wallop Bay issues, a blocker in Friends in Deep Places, and an item problem in Slugs in the Shell.
This was one of the most trophy-relevant early hotfixes. Official notes explicitly say it fixed clue-collection problems for Our Lesser Brothers and Secrets of the Shrew Shortage, while also cleaning up rebinding issues for WASD, space, and left shift.
The checked official note for v1.0.3 targets a launch crash at startup and a progression blocker in Curdsville where an evidence marker could fail to let players proceed.
The first public hotfix landed on release day. It focused on early achievement and interaction issues, including the True Beast Powerup achievement and a broken panel near the autopsy table in Powerpoint.
Platform Differences
The public record we verified is strongest for Steam, because the build IDs are clean and the official hotfix posts line up well with SteamDB. PlayStation 5 and Xbox Series X|S also appear in the checked notes, but usually as follow-up rollouts rather than the first version anchor. That means the same fix can be public knowledge on Steam before the console timing is fully settled in the same note.
There is one especially useful pattern here: the official v1.0.6 note says the console rollout is planned for the week beginning April 27, 2026, which is exactly the kind of detail players need when a Steam issue looks fixed but their console still behaves like an older build.
The checked hotfix notes do not give us the same neat version-number trail for Nintendo Switch 2. That does not prove parity is missing. It simply means the public notes we checked are more explicit about Steam, PS5, and Xbox than they are about Switch 2 version strings.
Trophy Watch
If your run cares about clue counts, side-job completion, or platform-specific achievement behavior, patch context stops being optional trivia and starts becoming route information.
Known Issue Status
The cleanest current improvement story is around clue collection and quest-blocking bugs. Official notes for v1.0.4 through v1.0.6 repeatedly target those two areas, and that matters a lot because those are exactly the categories that can poison a collectible route or a trophy run.
The public sources we checked do not maintain a neat unresolved-issues master list. Instead, they read like a chain of targeted fixes. So the safest current stance is this: several high-value launch problems were clearly addressed, but a cautious player should still keep manual fallback saves and stay alert around progression-sensitive objectives until the first major patch lands.
That is also why this page should be read together with the Platinum Guide and Walkthrough Hub. Fix history changes how severe some old warnings still are, but it does not magically turn a no-replay game into a casual cleanup game.
