[PC/MAC] Cannot Load Into Lots after Aug 19 Update

Hi, I'm not sure if this will help, but I started a new save without mods, and that got my game to work, but I can't load any other save file. I'm really annoyed since I've been working hard on a Medieval save file, and now I can't even touch it! I really wish EA would keep some updates optional and not force them on us. So far, I'm waiting for a patch day to come for Medieval players. All our mods seem to be affected, and major mods like the royalty mods are very important to us. There has also been a grinding halt to YouTube shows like Citrinesimmer's Decades ultimate challenge playthrough. I wonder what Citrinesimmer and the others are doing right now about lots not loading?
