OK - I got this error after some tests with two connected computers and CS1.5 and AMX X 0.16. Some HUD messages can't hit target client if he is specified in show_hudmessage after automatically kicking bot This client connected in the bot place has some problems with hudmessages and some other AMX X functions. Only these hudmessages (and client_print chat) are visible sent to all (id 0). The same problem is with welcome message (not visisble on that client connected computer). The problem is since build dated 2004.07.04 (dated 2004.07.03 is working OK with AMX X).

We will work with this...
[EDIT]
I found something at AMX X forum. Seems it can be not podbot2.6mm problem.
