Remove zombies and reset sim have been working, but I've been considering these mods to reduce the number of times I need to manually exit the game and take care of this.
I have very little lag outside of the 4 am - 6 am range, less so when there is no full moon. The 'resetsim *' cheat has been working on a temporary basis, and I've always been in the habit of saving when my sims go to sleep anyway. Long story short, I have the freezing in the early AM because of stuck sims problem as well as buggy adventure boards among other inconveniences. If I don't need Master Controller, I don't even really want that.
I'm considering downloading the mods Overwatch, ErrorTrap, and Master Controller. I'm new to mods and this site, which may be a problem since I just saw an announcement about moving site providers and downtime in these next two weeks, but I might as well ask anyway.
