no sims in game only houses

So i know that there are huge bugs since the new pack came out, I do not have this pack and along with everyone else am having issues, my game was ok, a few bugs like my sims being mean to each other occasionally and my game taking much longer to load, but this was easy to fix and ignore, i do have cc, but ive went through my files making sure they are all up to date.. they are fine.

When i opened my game again later on in the day i was playing fine until the game wouldn't let me select the sim i wanted to control in the household, i just thought it was my wifi so i restarted the game, but when i re-opened my game and went back to my household my sims were gone and the jobs, skills, etc boxes were all blank except 2 '@@'s. 

I went to manage worlds to see if they were still there and they weren't. i hovered over another household and all i saw was 2 blue squares going feral and glitching along with a loading swirl. i restarted the game again and now i cant even go back to the save i was in, it only gives me the option to start my save from scratch 😕

I genuinely don't understand how an update/ pack can be so broken and STILL be released...
