It also happens when there's a toddler on the potty. The sim gets in the shower and immediatly gets out. Same if they try to bathe another toddler while one is on the potty.
Alright, for starters: Wiping the cache according to those instructions did not solve the issue, unfortunately.
The shower used is the same as the original unedited lot, the "EZPZ Shower" from the Discover University pack.
Looks like creating a new save solved the issue so far- just means I'll have to transfer everything from my other game over to a new save file. Can't say it's not a drag but I'd rather do that than deal with the bugs.
If there's any way at all though, I'd really like to find a fix to the problem. Completely starting fresh would kind of erase a few years of playing the game and require moving a LOT of Sims.
