I've completed 9 questlines from the alliance map and, after finishing the Wincestre one, I came back to the alliance map and the East Anglia quest - which I had already completed before - was avaliable, with no other option being open (I havent done anything in Eurviscire, Lincolnscire, Glowecestrecire, Esexe, Suthexe or Cent). Once I commited to the East Anglia quest for the second time in the Alliance Map, no quest was shown in the world map. I've travelled to East Anglias main quest points and there's nothing to do. It's as if the quest is phisically done, but the Alliance Map doesnt recognize it now. Im still commited to East Anglia and there's nothing else that I can do. I've tried reinstalling the game, loading an earlier version and several other options. I've 90+ hours of exploration and It wouldnt be pleasant having to play everything through from the beggining again. I've been waiting for this glitch to be solved since november.
