I believe Davido's problem has been fixed. It was not a bug with the game, but a problem with something else.
"...many broken skills..."
many??
With the
patch, True Shot and the damage portion of Crossbow Expertise are broke.
Some people have run into problems with Aura of Command causing a crash after having worked for a portion of the game, which in a couple cases started working again later. A few people have had Repair cause crashes with equipped items, but found that it worked reliably with items on the ground or in the inventory. A couple of people have had problems with traps, summoned and resurrected creatures turning hostile, possibly in connection with mixing these. I don't recall hearing much about any of these since the patch was released, except a question checking if Aura of Command was fixed or not.
