Having BE issues with only one mod in it.

Hello, 

A few days ago, I have transfered a household that I haven't played with in a long while to another save. Since then, I have been having BE Issues. 

Last night, I was doing my 50/50 because of an holiday_service issue. But then, I got another BE problem until I just had Better Exceptions in the Mods folder. I did go to Discord and it said there was an problme. with a missing mod. with one of them, in which it said to Save As... and duplicate the save file. I did that and it worked. 

In the middle of all this I had 8 corrupted save files. I also had some more a couple of days ago. (Could this be due to For Rent. I only played with that pack once in the last couple of months).

Now I am back to the holiday_service problem with only Better Exceptions in the mods folder. I did try to do the Save As... and duplicate, but that did not solve this problem. I still got that popping up at the beginning of my game. How do I fix this and do I need to give you any corrupted save files? What do I do now?
