Thanks for the info. I have looked at the error reports before and tried to make sense of them. I think the problem is I run out of RAM because I play on an old run-of-the-mill laptop - nowhere near a gaming computer. Nraas Master Controller, reset everything seems to have fixed what was causing the problem. The only problem now is there isn't anyone at the food register in the grocery store, which I plan to replace with savvy seller anyway, and no one is at the consignment register. I'm going to wait a couple sim days and see if employees are provided. If not, I will delete the consignment register and try putting it back in.
