Is there a way to set the max number of bots in a game? I've noticed that I have the set bot_minplayers "4" and I have the max number of players allowed set to 16. Now when a player leaves I notice that a bot takes his place. Any way to fix that?

bot_minplayers is supposed to represent the minimum number of players that the server tries to maintain--with bots when necessary. So, normally, as long as there is more than 3 players on the server, there should be no bots. If there are bots, then there might be something else in your config that is causing that. Some admins manually add bots in their config and that may conflict with bot_minplayers.
