I think this could be usefull.
My game start to behaviour in the same way. I noticed it some time after installing new tuning mod, that need to replace
gameplay.package file in Game/Bin directory with the new one. All other mods I have are tuning mods and they are new objects, cloths, floor tiles etc. (except AwesomeMod of course). Well, searching in houndred of files for this one or two making sims in my neighborhood not eating or bathing is horrible work! I restored the original gameplay.package (made backup before
) and all came back to normal. Strange is, that game don't show any error messages and Indie Stone Compatibility Checker don't show any conflicts.
If you ever replace gameplay.package, restore it to original and all should be back to normal.
