[God Of Gaming]

Plugin is supposed to replace the team and faction selection menu with a custom one that would allow me to add custom player skins, potentially more than 4 per team. It appears to work in-game, it does what it's supposed to, but in the server console I see error messages and I don't know how to fix them. I even got disconnected once because of message channel overflow or something like that. Error shows up when a player connects, and exact error is:

Invalid message id
[AMXX] Run time error 10 (plugin "cs_beta20.amxx") (native "set_msg_block") - debug not enabled!

Here's the plugin code, help me fix it please
