Why don't you just set it up so that it doesn't force client to change it...but it runs a infinite loop of checking, using set_task and if client changes from dev 0 to dev 1 then it auto kicks them, and if they connect to your server it would IMMEDIATELY check what the dev cvar is set to and if set to 1 then kick, and print in console To play on this server you must have developer set to 0. Just an idea...this sounds good too me too so if anyone knows a quick way of doing this I would appreciate it too.
