I got this as a reply to something I posted on a Mac forum, it may affect PC players also.

There is one bug in the game you need to stay aware of. One so deep and subtle, you won't even notice it until you're trolling through your character stats. Whatever you do, don't doubleclick equip any weapons or items, it'll remove all the racial, class, and permanent buffs you have on your character.
