Bioware really has to patch these game breaking glitches such as when you fight an enemy and he sits down with 1 health left and you can't to anything. I've experienced this glitch 2 times on my Sith Maurader. 1 is at the end if the Hoth story-arc when you're supposed to kill Xererender and his master. The other one was when I faced Lord Draagh on the "Reallocation" quest. I defeated him but he sat down the second time with 1 HP and there was nothing I could do. Please patch these types of glitches Bioware.

At the end of the Hoth quest where you hunt down and kill Xerender and Master Wyellett, when I defeated Wyellett the second time he goes down to 1HP but doesn't die. He just sits there and there is nothing I can do about it. This is a class mission so I can't abandon it. Please help
