I'm on a level 4 character who is ready to do part 3 of the Waterworks chain. There's an LFM up for that group - in progress. I join, but when I try to enter it tells me (Error): Each member of your party must meet the requirements for this quest. I try a couple of times. I recall, drop group, go talk to guard whathisface to make sure I"m on that part, and I am. When I tried to enter it said the adventure was in progress. I rejoin, try to enter again, get the same message. The group had two level 5s and a level 4. All of the requirements are met, so why won't it let me in the **** dungeon?
