When trying to load Buried with the mod active, the game will crash during the intro cutscene, going back to the lobby screen and displaying this popup:
Error

Buried is the only map where this happens. For some reason, loading into map without activating the mod in the modmenu will let it work just fine, only like half of the mods changes like new HUD elements and specific balance changes will actually function.
