The alpha crashes when one barney shoots another

[pmtk_milk]

Well I think that in Quake there was friendly fire and the enemies killed each other but in Alpha 0.52 it happened to me once when I provoked a Barney who was behind another Barney (On the maindemo map) the Barney wanted to shoot me but he shot the Barney who had not been provoked. Is there any explanation for this?

It's an alpha that contains early AI that was thrown away during the great rework of '98. Don't expect it to work properly.
