So this random queuing into a completed dungeon then getting a penalty timer is much fun. What year is the ETA to fix this bug? It definetly is NOT new, I suspect it's been in the game since launch and probably beta.
There were a couple posts about this recently that I saw and commented on. They know about it but fixing anything with the activity finder seems to be extremely difficult for them. I blame spaghetti code.
