[OPEN] [DU] Roommates get replaced in dorm often

It's still there and it's really annoying. It doesn't happen in the dorms that are on the high floors (penthouses), but in the small ones. Every time I restart the game, change something in CAS, or when I change something in the community lots in build mode, the roommates change. I cannot maintain a lasting friendship with any of them, because they are always different.
I should add that I set the lot as affiliated with one of the university organizations.
