Sims 4 update and high school years errors

So Firstly prom doesn't work with my game at all. I had to turn off aging from prom to even show on calendar for me. Prom never loads I removed MCCC after that was reported as causing issues with prom. Secondly I lose progress in saves after I save the game and after deleting MCCC now my save/game will not load at all. Loading screening will come up and will just pretend to be loading like spinning plumbob and text will come across but after 20min save never opens. I have tried to load other save as well as recover the same save and the recovering recovered a save from 3 saves ago and still will not load the save. Please help
