Happened to my group on my DK earlier. Tried reseting, killed all the other bosses, reset again, nothing. Closest train just get stuck and then Operator just sits there yelling about the rest of the train's movements. Thought we just got unlucky, but every group I've tried to join today has had the exact same issue. Hopefully it gets resolved soon or by tomorrow but I am guessing anyone who can make a hotfix has gone to bed. Hopefully work gets canceled Thursday due to the heat lol.
