I installed as the instructions said, got the error on the main screen that the game couldn't write info to the story folder, went in with bodypart edits just to play around... is that what toggles the achievements off?

Weird, cause the mod works just fine in the version of House Party I have that isn't attached to Steam.

So, does this mod break achievements popping up in Steam? As in, I've installed this mod and gotten nothing in game while completing achieves, so I remove the mod and start over, and achievements still don't pop...?
