my own units killed each other
marauders just started killing all my own units, hero unit even
I could not stop them, was not lagging, I watched in amusement as they killed other units and when they ran out of other units to kill, they shot arrows straight up into the air and killed themselves
while doing this they never missed, and the arrows did much more damage than they normally would of, maybe the damage was part of the never missing? No arrows would go into ground, they all hit.
