I have seen this happen a number of times when one is under attack it runs then crashes into a asteroid or tries to run around it. When one or more have been hit and there is only bots left and a few really players all bots are hitting rocks and doing nothing.
Also noticed if all players lose the battle and down to the bots then bots if one size has one sector taken over from human players it will finish it off if you have no bases taken then the other fraction and side wins.
Little bit of a bug there and also an exploit that needs to be fixed.
