Last Exception From MCCC
Hi, I was recently having an issue in every new save file I create where when my sims travel to community lots, there are no staff or townies there at all. I thought I fixed the problem after removing a mod I thought to be causing it (Turbolib Simulation Unclogger), and the game worked fine and then it started randomly doing it again. I tested in multiple different new saves and it was still happening. I have been trying to fix this for days and cannot find a fix. I even tested the game with no mods and it was still doing it. I found that I keep getting this LE whenever the problem happens.
