Black Screen, Sims Still Active, Can't Close
Since the Sept 18 update, my game has been moving slow and about 4 times now the entire screen turns black, with the exception of the conversation bubbles, progress bars, and the bottons at the top. It won't let me click the ... button, it won't let me go back to manage world (I can still see that button), but I can still hear them talking and using items. Every time this happens I'm unable to close out my game or even shut it down from the main button at the bottom of my Mac.
I play vanilla and have no cc and have never had mods in my game.
I play on a Mac Pro with 2 terabytes and before this update I haven't had problems with lag.
I have tried repairing my game, shutting down and restarting my computer.
I own all packs, but was playing only with base game using the pack selector.
I hope that's enough info. I'm not a techie person.
Thank you!
Edit to add:
This is what the screen looks like right before it goes black:
Notice all the playable buttons and such are all missing, and so are a couple of the top buttons.
