Ricalynn, that sounds like a problem a lot of people reported in Bridgeport, where people would just keep dropping whatever they were doing to go stand around the lot at one of the bars. I remember someone said they bulldozed the bar, and the people would go back to stand on the empty lot. Resetsim * resulted in what you reported - everyone went home, and then came right back.
I hate to say this, but I don't remember if a cure was ever found - you might find something if you search the forum, though.
