Diff 9, standard settings, I had just fleet wiped on a 250 strength planet with the intention of spawning dark spire ships to clean it up.
I think these were the first recapture waves aimed at a planet I already owned, about 5 1/2 hours into the game. There had been a couple of small (~10 strength) waves to neutral planets before that. The planet they attacked was fortified to 90 strength between turrets, a battlestation and zenith trader goodies, but there were other accessible planets sitting more around 30.
I'm not complaining, I got the best part of 6,000 zombies out of it. Just interested to see if there was some sort of hitch in the logic that has gotten to 800 strength and dump it all on the strongest available planet.
Am I missing a setting to enable writing the AI decisions to file? Always used to like spelunking those logs in AIWC to see why the AI made it's decisions. Especially the hybrid logs.
E: Oh the command station thing, the bug is that it preserves the theoretical level of the last built station and applies whichever is higher between that and the actual tech to the new one. So if you have Mk 4, 2, 1 military, econ and logistics you get can build a MK4 military command. Replace it with econ, get a MK 4 econ. Replace it with logistics, get a MK 2 logistics. Replace it with military, get a MK 4 military. Replace it with logistics, get a MK 4 logistics.
