Left 4 Bots 2
Bots avoid try to shoot boommer any problems
I have two problems. The bots keep shooting Boomers when they're near me, and they make a beeline for the safe room when close regardless of how dangerous it is, especially if there's a Witch in the entrance. I can't seem to find the settings in the text files, but if I somehow missed it, what settings should I change?
