Not sure where to put it so it will go here ...
I was playing with the standalone on sig11's SitW-DM. Hellrider tried to connect and left the beta2.2 in his WQ dir. I got the message "unpure client detected invalid pk3 referenced blabal) and got kicked out (game was frozen, nothing happend). Another player (playing with the normal mod I guess, definately not with the beta2.2) got kicked as well. Went back in with the other guy and hellrider and we could play just fine.
That happend before as well, but I thought it might just be a "bad luck" or one of these days. But now we might even be able to reproduce it.
I never had that with older version, so I guess that it is somehow related to the beta2.2/standalone.

... so I'll probably install a version which is a bit more verbose (both to the player and to me) in this regard. Oh, and the exact error messgae is "Unpure client detected. Invalid .PK3 files referenced!" - I hope that's what you saw - otherwise I'm digging in the wrong corner
