AI Stops building trucks/structures & stops doing research.
In Skirmish mode against an AI(one or seven), a few but not all the AIs will stop building trucks & structures & doing research. The trucks will just sit there if you attack & destroy some of the base. The AI will not move to repair/rebuild anything.
You can also tell that it isn't doing any research because other AIs will be at auto repair except for these few. This isn't because the AI is slow. I play VERY LONG games(days).
Sometimes it happens to just one AI, sometimes it happens to more. It seems to happen after a long, drawn out game, but before the AI gets to auto repair. I don't know what tech it stops researching at, it is just that I can see visually whether an AI has auto repair. It just seems as if the AI gives up hope at winning.(I like to give slow & painful deaths )
