A few extractors, a couple of power generators and then the AI will decide to just give up on life: It was the same ten minutes later and it happened again in the next encounter (but not the one after that which actually kinda threw me).
You know, the poor AI has to do this day in and day out, without a break. While I don't advocate sleeping on the job, certainly you could have some sympathy for it!
What difficulty? On the lower difficultys the AI gets less resources and fewer brain cells. Although if the lower difficulty commanders could at least do some commando actions, like attempting to combox. That would be too legit to quit.
Yeah the normal AI sits still for most battles. Although im not recommending you jump to absurd, because then you fight 2 fully sentient AI's.
