Sorry for the lack of details, but I was pretty pissed and wanted to give the problem into someone else's hands,
Here's what I figured out:
The problem arizes in realistic mode, as a bot picks up the stat gun, even before seeing an enemy (even if there is no enemy on the oposit team) he will constantly shoot at the same point (at the floor). And since the bot is not looking in the direction of the enemy, he cannot see him. And as you said, if the bot does not see the enemy, he shoots in the same spot.. over and over again :\.
I need the bot to either have the ability to see the enemy from the tower or point the bot, as he touches the stat gun, to the enemy's spawn.
thanks
