Problem in The Sims 3 save (Sims University)
So, i play The Sims 3 for such a long time, and honestly, i've never seen anything like that, and i don't know how to resolve.
I was playing in the Sims University with my second generation of my family (one of the first generation have been in the university of the same save before), and while my sim have finished his final exams, with high grades, i noticed that i didn't received a notification saying that he graduated, and because of that, my sim had to go to the class again, even if it was showing in the academic achievement that he did pass with an A grade.
Not only that problem occured. I have the Nraas errortrap, traveler, saver, master controller and overwatch, and probably because of the overwatch specifically, the sims around the Sims University started aging up, even the ones in my dormitory, making them selectably to me, but not showing their interfaces, just of my sim. I even received oportunities to do from them.
The third problem: A climate stone spawned in the Sims University, and i noticed that after some more hours playing without seeing the error, i clicked to edit the city, and the icon showing my home (Isla Paradiso on the save) had gone, and i realized that the university turned into the original homeworld.
And finally, the last problem. My sim can't go back to Isla Paradiso, and i tried with a backup of the save that was minutes before i saw the third problem, and in that save the home icon still shows. Even with my sim quitting the university with the phone, he still stays there, but without class, and with the possibility of taking a job at one of the two places at university, theater and restaurant. The bonus part: in this backup save, i can go to Isla Paradiso, but in there, i can't do nothing, because my sim is at university, and strangely, the home icon still shows in Isla Paradiso, and when i clicked it, a pop-up showed saying that i needed to put a base in the town to go to edit home (like the bases at World Adventures), and even putting a base in Isla, the pop-up shows not on the home icon, but at the Oasis Valley, Shang Simla, and others icons at he top-left corner.
In order, the second problem occured first, then the first, third and the forth. I have all expansion packs and high-end loft stuff pack, and i don't know how to solve this. I thought about putting a Sims University from the backup folder in the game's documents folder, but i don't want to corrupt even more my save, if it is a sign of corruption there.
I hope you'll can understand this complicated problem and help me! (I'm brazillian, so i'm sorry for any language error)
@GabGGT17 When Overwatch started aging up sims, that meant that the game was already confused about the homeworld. No sims should age while your sim is at University, or on any kind of "vacation," so the fact that they did means the game was no longer treating this like a vacation. Overwatch was simply catching sims that should have already aged up, according to the usual game logic, not making them age in the first place.
I think that all the problems you've described are due to the game treating University as a homeworld, with the possible exception of your sim not graduating. And the problem here is that if you don't have a backup save, it can be difficult if not impossible to fix this issue. However, what you can try is the Change Hometown process described here:

Please make sure to follow the instructions exactly—missing a single step can corrupt the save. Use "save as" to rename your save, so the current copy remains intact as a backup, before you do anything else.
I'm not sure from your description whether you can pick a place for your sim to live in Isla Paradiso, but I believe you should be able to choose somewhere to stay even without being able to edit the town. If that's not the case, let me know; there's a workaround for that too that may or may not help.
