Once you join & leave a league, this reappears when standing near TPs (and possibly portals? I've only been near one since the patch.) and leaves when you're out of some (protection?) range. So maybe this has something to do with some text associated with them? (Already discussed in the presence a CSR.)

Problem: Guild names such as Magic Buffer Guild or Wanderer Patrol 1
Solution: Join a league and then leave (lasts until port or log?)
