I get this bug now as well on my dedicated mEAn PODbot server. The maps I experience this on are de_nuke , and as_oilrig. In the past I had this bug when I first started working on getting POD up and running on a 1.6 listen server. The error at that time would occur the instant the bomb was to drop out of the hand to the ground. I fixed this problem by reinstalling metamod, podbot, and amx. Anyway I haven't spent alot of time figuring out why its happening now, I know it doesn't happen on the map change. There is deffinately an action that triggers this kind of error. Wether its a sound that gets asked for or what I'm not sure.
