I've had this problem for a while but since i normally play with random enemies, I wasn't sure which kind of AI was the problem. After some testing ive figured out that it is the fortifier AI. at least on hard difficulty, it seems to never want to leave its home planet ever. It builds several colony frigs but never sends them anywhere. As an ally i told them to go attack a militia own planet one jump from their home, and while they sent combat ships to wipe out the locals they then left without colonizing it. Is this a known issue?
