Corrupted Sim?

Hello!

So today, I wanted to play my Save File (first screenshot, error code 110) everything was normal until I tried loading into my Family. after a while, it kicked me back to the Select World Screen with the Error code that you can see in the Screenshot. So naturally, I closed the game and removed my mods folder to see if that will help and cleaned the cache + repaired my Game. Then I opened my Game again, tried to load into the family just to then get stuck in a forever loading loadingscreen. That was weird to me because 3 days ago I played this save file and it worked just fine, since then I have deleted ALL my build/buy custom content, added new clothing CC and used a program to chang all the CC names so there is no special letters or anything (I have never done that before, so I dont know if that might be the issue here, hence why I am mentioning it.) I have not removed any script mods or anything like that (important for the next issue) So after nothing worked, I tested around in the save file, I loaded into a few families, and it worked. Then I got hit with another family where it didnt load and I got hit with another error code. Okay, 2nd family thats broken. Tried around more, found another family. So then I was thinking and decided to see if its the family as a whole, or maybe just a sim from said family thats broken. I split my first family up 1 by 1 and loaded into the lot i moved them to so I can see if these sims are "okay"  first family had 6 sims, so i tried 6 different sims and 5 of them, the game loaded just fine. So I knew, okay, its 1 sim from that family thats causing the error. I added her to the family after to see if anything is different and then I noticed that she lost all her Milestones she has gotten throughout her life (infant-adult) So I thought I should check all families where it failed to load if the issue is the same, and it was. All sims where it gives me an error code to load into the family, have lost their milestones, but how? I didnt remove any milestone related mods, i didnt add any milestone related mods. So my next thought was to just test in a completely new save file. I started a new game, got my sim from the gallery and then the next surprise hit me, it wont load there either. No matter what version of the sim I try (I tried teen, young adult, early version of her adult life) it never loaded. So not only are these sims broken in their current save files, they are completely corrupted even when I get them from my gallery. I have no idea what happened and I am so confused with whats going on.

Now the 2nd save file ( screenshot number 2, error code 121) That save file is still pretty new, I havent even played a full real life week in it.) Everything was fine there 2 days ago when I last played. Today I tried after all the testing on the first save file, and got stuck in a pretty long loadingscreen (it usually loads pretty fast) but I waited it out. Then, it finally loaded, and I get error code 121 and see that while I was in the loading screen, the game resumed time so the moment I press Ok, 2 of my sims would just die. Same thing here, I tried without mods and cleared cache but without any mods in, it wont even load me in so I will just get stuck in loadingscreen. Because it loaded me in overall, I tried in a new save file, first with only my founder from that family, which worked fine. And then I tried the whole family, and got hit with another infinite loadingscreen, so save to say there seems to be another corrupted sim, or it was because I tried it without mods but either or, it should still load, right? 

I hope somebody can help me because I am really lost on what to do, even if the saves are overall corrupted, i wouldnt mind that too much, its just that I cant even use these Sims anymore because they just seem to be completely broken ):
