You get bots in a team if you set preferred players to a number that is higher then the amount of players there are in the team (you can also set the maximum amount of players to 0 to make it a complete bot team).
This won't work for my purposes. I want to use bot events on them, but I can't because they don't have a hole. Also, for things like Fort Wars, this REALLY won't work. That's not to say it's a bad feature or the wrong way to do it; it's wonderful for a lot of purposes, just not this one.
And while I'm whining about bots, I'd like to request that you can set the uniforms for players and bots differently. Maybe bots could ALWAYS use Full while players use whatever setting you have on? I want players to be able to keep their avatars without turning bots into shadows.
