Map: Mork's Mire.
Has happened twice. Opponent drops around minute five or six from raging or d/c, AI takes over.
The ai sends one servitor to a shield generator, and then ceases to do anything else.
This is minute six in the game. No structures are damaged, no shield generators are down. The AI did not have any player controlled units except for the servitors as they were destroyed before he quit.
The ai takes no further action for the remaining ten minutes of play, no building, no unit production. Some slight servitor movement and an attempt to build a listening post but that's it.
The AI should have had access to some amount of resources. I managed to hold two nodes for about six minutes outside the one that's located behind turret protection.
