Forum:HELP sticky situation

hello im playing on my main character lvl 50 roland on xbox live has almost 15 million experience and needed one claptrap rescue and the mad moxxis underdome missions to have 100% completion also a few challanges now i clear the claptrap mission and go to find a game with underdome i join one but its not under dome and 3 new missions are added that i already completed 1: Claptrap resque old haven 2: Talk to tannis 3: a claptrap rescue but i cant remember where

so i think #"!¤ a bug oh well guess ill have to clear that all over again so i clear the claptrap missions but then i go to the crimson fastness and i go to that cell where she was when i was originally on the mission but shes dissapeard it says turn in and the compass say at the cell but i cant turn it neither can i continue to the ECHO devices of course because i already have done them on 2nd playthrough {`´o`´}

Then i asked around and was told that if i joined someone on the same mission and they completed it or something like that it would be resolved but i cant seem to find anyone to do it with if anyone wants to help please write what you think might help me or if you can add me on xbox live my gamertag is UberDanger please write back soon {´`o´`}
