@simliciouss1 Thing is, this issue of not being able to load lots (where a family lives) is something I ran into quite a few times already. Usually it's fairly easily fixed by evicting the household and moving them (or another family) back. Haven't had it happen before that the player 'moved out' the household using a mod though... 🙂
I do think you may have corrupted some of the lots (not the save per se, but the lots) by trying to fix them. If evicting/moving in does not work to be able to reload the build, try replacing the build with a different lot, then moving the family back in. See if it then becomes loadable 🙂
