Aw yes... the quest that has you running all over the TOA area. it is the only quest that has NPCs "doing stuff" but they are not animated doing that stuff. It is unexplainable. Just take a look for yourself. There is two other white lines like this and there is no animation for any of them. Also when you finish the quest the dude that was stuck in ice... is still stuck in ice. The things add up and I think that it is time for some sort of update.
