Sims won't interact with objects or each other

I have done everything that I have found in these forums, nothing has worked. I play mostly with hair and clothes cc and two mods (now four, because I installed two to fix the dining and the knitting and both worked), the dining is still funky even with the mod. Today, they added something thar appeared on the Main Menu, since then all my sims and visitors stand around, not listening to any commands, then I can't save out of the game so I had to restart my computer. It is becoming so hard to play, you know, you have to do so many things with your game, and it's different with every bug in every update (in my experience, it is always a problem with the Update), it feels that I have to work more and more to fix a game that never gets fixed. DX11, Reaper's rewards, knitting, the dining and now the sims going on a coma and the game on a never ending screen...
