I'm normally a PvP player, but run some PvE dungeons from time to time - especially some during this Undaunted event. Ordinarily I don't have any real issues with the group finder, but just had a solo random queue plop me into a dungeon without being in a group. There were 3 other players inside, but they didn't respond to messages in /say, and I obviously started with a countdown timer that was booting me from the dungeon. Once I did in fact get bumped out, I was stuck with a > 12 minute cooldown timer before I could queue up again.

Is this a recognized bug? Or did I perhaps get vote kicked before the dungeon even started, while on a loading screen? Maybe 3 friends/guildmates wanted the random bonus for queueing, but without actually having another player around...
