ToME: the Tales of Maj'Eyal

So as a Berserker, I got 2 levels of Unflinching Resolve from escort quests. I wanted to put some more levels into it, so I put a talent point into Vitality. I had recently put in a few levels to War Shout that I wanted to reallocate. Imagine my surprise when I went to unassign the points and it tells me that I can't because of Unflinching Resolve.

Prior to this, I was able to reassign talent points without a problem. It looks like putting the point into Vitality is what caused the problem.
