Bioware's pumping out the patches, of course there is a slight problem. 1.22 is out, but it's BETA.
The intellect devourer thing is obvious (but is limited to single player). The skill list bug was introduced in 1.21, but we don't see it that much in multiplayer.
Most importantly, it says they fixed 3 (3!!!!) memory leaks. That's a big amount of leakage going on :P This is obviously a nice fix for those running full-time servers (Ala Gris and disc).
Oh yeah, since it is beta, if any servering updates they should post saying so :P
Since I've been more on WC3 lately than NWN, I can afford to wait for the official patch unless I want to join a specific session.
