I've had the same thing happen. I think it's because you haven't dropped off their rivals list and they have dropped off yours. So if you are punching them and attacking them and they do nothing to you, your attacks get continued on, but theirs wont. So when they do attack you, their's will start all over again because there not already on your rivals list. Or something like that.
