After killing Ustrain (which took me almost 2 days, by the way....easily the toughest fight in the game for me) I got stuck in the place he teleported us to for the encounter. Did anyone else have this issue? I had to reload to a previous save and not do the encounter to go on. Any help would be appreciated, thanks.

I am having exactly the same problem. After trying to install the latest (mind you my party is level 23 and it was still impossible) I got v3.3 now and after killing the b*****d I am stuck. Any help at this point would be appreciated
