You have entered too many instances recently.
Has anyone got this bug before? I was farming FoS normal with a group (not rdf) and on the third time we tried to run it, I ran back out in the beginning of the instance after our hunter pulled the first two skeletons (smh.) After that I tried to run back in but ran through the portal and got this in chat: "You have entered too many instances recently." Has anyone had this issue before? I've reset, relogged, and reformed the group all to no avail. Any way to fix this?
Edit: waited about 20 minutes and was able to enter dungeons again. Would still like to know what causes this.
