University error code(s) 123 when traveling to outside lots (i.e.Darby's Den)

I created a copy of the old save file, although I keep running into the same issue. Eventually the guy from the household I was playing was able to graduate, so hopefully I won't run into anymore errors there, but I recently changed to a different girl enrolled in university and I'm getting new errors not related to the game failing to load. Not sure, but maybe I just have a corrupted game save? I'll try playing a new save file without mods and see if the problem is solved.
