Can't change levequest difficulty (possibly due to NPC being under attack?)

[Mychael]

Oh, I haven't done a GC leve in a long time so I guess I forgot.
Well anyways, it's a bug that happens from time to time that mobs don't de-aggro. You have to go back to them and get aggro again to fix it (or at least that's how it works for me).

I tried, but the NPC I was protecting died before I could run back. :,( So I thought I'd report it, and maybe they can fix the bugs. ^^;
