I've been having a problem since the installation of University.
In my first game file, I sent two Sims that I had played for a while on a two-week term to Uni. No problems while at University, both arrived home fine, all sims in the household were working. I played the file for a few more hours then quit the game.
When I next started up the game, none of their faces were appearing in the User panel. I could see them all, but none would do anything. I could add and cancel things from their queue, but they would not move. I tried resetting each sim, did not help, so I tried resetting the whole town, also did not help. Turning testingcheats on, I could not shift-click them. It was like they were not even there! Their motives would not drop, and they had no moodlets, and the ones who had high moods, would not gain any LTHP's.
Eventually I gave up and deleted the file.
Then I started a new file. Spent a few sim days working and skilling, then sent this single sim off to University on a one-week term. All goes well at Uni. Upon arrival, she has no portrait, and is having all the same 'stuck' problems that the sims in the last save were having.
Any suggestions?
I do not play with any mods. My game is fully patched. I have a considerable amount of store content.
EDIT: Come to think of it, this began after I installed the new store venue, the Cinema Plumbbob. Don't know if that is causing the problem or not. None of the sims had ever visited the lot, however.
