exactly....
I didn't give bots the ability to changerace...this would require some kind of KI

On first join, he picks a random OPEN race, and thats not predator, because it has a required level.

Well, I could code something that every re-join the bot thinks about picking another race *g*
or maybe in admin menu, that you could toggle the bot race ? that would be a good feature !

Yeah, an automated process would be good, i can even see how it would work.

Set up a counter on map_start, a random variable per bot, which is between 1 and say 7, and at that specific round (each round -1 from the counters) you do a check for changing race. Eventually they should become high levels in most races, but they'll be changing all the time, will add a cool effect.

You'd have to use keygroups though to make it so that each counter is per bot, that way not all the bots change at once, some change in the second round, some in the 5th, etc. Adds some cool realism, and also lets them use races which have a required level
