[quote name='nbballard']Does anyone understand how the shops work? One of the shops had an awesome cleaver, and by the time I sold stuff to make room for it, it was gone. My system time said it was 11:01, so i figure they rotate on the hour, or every 15 minutes or something.[/QUOTE]
It changes when somebody levels or when you enter a game. Otherwise they stay the same forever. I *think* they change when you load a checkpoint, but I've never tested it. There might be other factors, but that's all I've found from experience.
