Getting Last Exception Errors and Corrupted Saves

Hello,

I don't know if this is a bug, or it is caused by For Rent, but I have been getting these issues related to a NPC or a Sim that I played recently.

Yes, I do use mods. But today, I took them all out and I got 21 save corruptions. I have been doing a 50/50 on my saves (Not my mods, since I haven't put them back yet) and I am still getting Last Exception Errors with more Characters affected.

Should I give you zipped version of 2 of my corrupted saves?
