It seems that one way to go is using MC to delete them all, and then letting ErrorTrap remove the new ones every time the game loads. Seems there's no complete fix for it yet.

EA seems to have enclosed some wish fulfilment bugs sometime between UL and IP. One of these is the "Throw a Party" and/or "Throw a [positive adjective] Party". I've tried throwing parties left and right, both at home and on community lots, but neither wish are being fulfilled. I've found similar reports from as early as May 2013, and some people got the problem fixed after installing IP, and some (like me) didn't. Any chance you could check into this?

I'm running latest patch/AM with all EPs.

Hmm, CustomClothingFilterIsDefault doesn't seem to work when enabled. I assume it's supposed to hide all non-custom clothes and accessories in each clothing category, correct?

Did you buy the game(s) through Origins, installed it from disc(s), pirated it, or installed it through Steam?

I don't see why you feel the "Packs" folder is an "extra" folder? It's supposed to be there.

Actually, I just gave it a try and it seems "setfitness/setfatness" won't work with the selected sim, it gives the "no sim by that name" message. I tested this a few times with random sims, and I could always fitfat any other sim except for the one selected. Or maybe it's meant to work that way?
