Stuck on a Loading Screen

Ever since the May update, I've been getting stuck on loading screens when loading the save. I've run out ideas. I've tried deleting folders, deleting some save versions, took out all of my mods, and even tried on different saves. 

The only thing that works is different saves, which I'm assuming means it's a problem with my main save(the one the issue is occurring on). 

If it helps, I'm on Mac, using the EA app, and have an exception. Here it is:

Hi DragonMixie​ 

you seem to have an issue with a milestone that was on a cc that you removed from the game.
