[DU] Sims can’t move back into the same dorm

I ended up figuring out the issue months later, but forgot to update this bug report. I had initially used enablefreebuild to edit the dorm in another save, then placed the lot in the save I was playing in once my sims were at university. 

For some reason, placing the lot in another save (or maybe cheating to editing it — but I haven’t had that issue with other edited dorms) caused it to set the housing option to Foxbury instead of Brichester. Once I selected Brichester housing in build mode, I’ve been able to play in the same dorm without moving out in that save with other sims.
