White screen of doom

I got the white screen before the update, I was moving in and out different apartments in San Sequoia. And then changed it to back to residential.  I got out of the lot and when I tried to get back into the lot in San Sequoia it was  impossible because all of San Sequoia is a white screen now.  I deleted the save.  I was told that save corruptions can spread if you go into another save unless you totally get out of the game it’s self and reload the game.  I thought it had to do with changing lot types.  The white screen issue has been around awhile.  I was luckily working in build save testing things out, but I’m afraid to change any lots on my main saves now.  It’s a big problem for me.  I hope the Dev team fixes it soon.
