Official announcements, newest first. Posted on Steam.
- Community Announcements2026.7.19DA+0.2 doesn't actually accumulate — the dopamine is reassigned and capped each time (not added up), so rapid clicking won't pile it up or make it run wild; the only thing that really stacks is intimacy. This update added a minimum interval to petting during courtship/grooming: rapid clicks no longer count repeatedly, but the dance isn't interrupted and it feels the same.
- Community Announcements2026.7.17 Update NotesFixed a bug where the "Mother"/"Father" dropdowns in the Breeding Lab closed the moment you opened them, making it hard to pick a mate. They now open normally.
- Community AnnouncementsUpdate Notes — July 10, 2026🛟 Important fix: a thawed fly disappearing after a restart Previously, a fly you'd thawed from the cryo chamber could — after closing the game and reopening it a while later — occasionally vanish from your desktop and be missing from the cryo chamber too. This is now fully fixed. And most importantly: her data was there the whole time — it was never truly lost. After updating, just open the ga...

Why FlyMuse mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host FlyMuse mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
