AI just sitting on its hands

I haven't seen any posts about this, and I assume the enemy AIs are not fully implemented. I've played multiple games were the AI does nothing, even on hard. Doesn't colonize new planets, doesn't attack me, just sits at it's home world had does nothing. It will build some orbital facilites and ships, but then it stops. It even stops sending out scount frigates. Furthermore, it will not expand to other galaxies, it wont even explore them. I let a game run for 4 hours (5-6 hourse total) after discovering all enemy positions in a 4 star galaxy. All the AIs did nothing, one was even wiped out by pirates during that time. Anyone else having this issue?

Other then that the game has run great. Just some small visual problems that have already been mentioned. I've had no crashes at all, nor have I had any of the problems metioned in other posts.
