Hi all

I'm experiencing a strange issue with my game.

I rebuilt Drake Hall - spent 3 days!! ☹️ - and am able to place it on the map, but my current Sims who are living there cannot move back there when re-enrolling for another term. It doesn't show up on the housing options. I've also tried making a new household and when they enroll to UoB, Drake Hall isn't there either.

I thought there might have been an issue with my build, but when placing a new lot from the gallery onto Drake Hall, the same thing happens. 

I had mods installed on my game, mainly clothing and UI extenstion, but not many. I've tried with and without. This started to occur the day before the latest patch came out.

I'll attach a photo, but the halls I built appear see-through on the map, or sometimes with a black box around (I've noticed this on other builds I've done, but have never had any issues).

One final thing I should mention is that my game has been crashing a lot recently. I have a 2012 Macbook Pro and it gets quite hot when I play, but I've never had any issues. It happens mainly when I'm in Build Mode. I would love to know if this is a game issue or I just need a new laptop.

If anyone can help, that would be great 🙂

Thanks!
