On adamant, the AI has a tendency to use colony types that they haven't researched yet.
They were never able to use the colony ships to colonize planets. They would just design and build empty ships. This has been fixed though, many months ago...
I was not aware that the AI designs could violate player restrictions and still get built. This idea sounds neat. I think I might enjoy playing against the "Cheaters".
