I did the whole ** quest and I warped to bajor (just clicked on the mission popup) and it says "go to ds9" and I have to do the whole quest again!
I had been suspicious about quest popups for a while now, they say "abandon quest" when you just warp away to the next quest location. This time I wasn't paying attention and i clicked. This is a bug that's very easy to fix and extremely annoying to players. Just fix it and make less people ragequit this game...

Yes, this is a known - and highly annoying - bug and has been for a while. See one of the existing threads: http://sto-forum.perfectworld.com/sh...d.php?t=272234
