Well here's a fun one! I'm going to guess caching issues. It happened when I clicked on the "Art, Music, and Writing" forum section. So this isn't a topic that I was clicking on. Never seen this before.
It happened again only this time when I went to page two of the tavern. It may actually be a bigger problem then I though because a refresh and even going back to page one and then back to page 2 did not remove the problem.
