Re: Sims 4 game loads black box over house and turns black during gameplay

I experienced this issue today while building. There is a LOT of CC on the lot but this (below) started spontaneously while I was using a Basegame terrain paint outside. 

I stupidly saved while it was happening, and when I reloaded the game everything worked fine except the thumbnail for the house looked like the one in the OP

Here is my computer info:

I was able to resolve the issue (I hope) by rolling back my save to before the glitch occurred. Hopefully it won't happen again.
