MenuLibFix
Compatibility fixer for MenuLib 2.5.4 on the current R.E.P.O. build: re-installs the broken UIMouseHover / StateClosing / StateInactive hooks via Harmony prefixes, eliminating the InvalidProgramException spam.MenuLibFix
Compatibility fixer for MenuLib 2.5.4 on the current R.E.P.O. build (2026-09). Same companion-plugin approach as BetterMapFix: MenuLib itself is left untouched, a sidecar plugin re-installs the broken hooks via Harmony prefixes.
The problem it fixes
MenuLib rewrites game methods with MonoMod IL hooks + IL pattern matching. After the game update the compiled IL no longer matches, producing invalid IL:
InvalidProgramException: Invalid IL code in (wrapper dynamic-method)
SemiFunc:DMD<SemiFunc::UIMouseHover> (...): IL_00e7: stloc.s 13
The exception aborts MenuLib.Entry.Awake, so the MenuPage.StateClosing and ChatManager.StateInactive hooks never get installed either — every mod depending on MenuLib runs crippled (broken in-game settings menus, etc.).
What this plugin does
| Patch | Approach |
|---|---|
SemiFunc.UIMouseHover |
Full port of the current game logic + MenuLib's custom scroll-view check, as a full-replacement Harmony prefix |
MenuPage.StateClosing |
Current game logic ported, with MenuLib's custom-page slide-out positioning and cached-page preservation inline |
ChatManager.StateInactive |
Skips the original while a MenuLib input field holds focus |
All member references are compile-time checked against the current game assembly — a future game update will fail the build loudly instead of corrupting IL at runtime.
Requirements
- BepInExPack 5.4.23+
- MenuLib 2.5.4
