Deadender AI's

I've noticed that in every game there's atleast one AI that seems to play dead. I never use neutral AI's as they're a waste. I've seen that in every game one of the main AI's plays dead and acts like a neutral AI never expanding out of it's home system. I've had one that got to 11 colonies and then just stopped. Not a single ship or unit has been built by it.

I've also noticed that after about a 100 turns they seem to go to sleep. Seems like they choke themselves with too much ship building then hit the resource limit wall and then stop doing anything. Got a couple of AI's doing a little bit to expand but several are just sleeping on the job not building new ships or colonies. Got to stop this AI midlife crisis stuff so that they keep expanding if they have room to expand.

The other strange phenomenom I've noticed is that sometimes the AI's park fleets in the middle of nowhere. I had one where it had 2 fleets of 37 and 20 Dreadnaughts just hanging out in one system at the fringes. In I come with a recon frigate and proceed to wipe out every one of it's colonies and those fleets never moved to protect the colonies. Tens of turns later those same fleets were still in the same hexes, although one fleet got reduced by 8 Dreadnaughts due to the resources I trashed earlier.

I've seen the AI build Ship Training Centers yet never park ships over them to increase ship experience. If ships aren't moving they should be parked over colonies to protect them and hopefully Ship Training Centers to improve themselves.
