I've managed to browbeat one of the AIs into researching Rock Colonizers tech to level 10 by 2401.2, with minimal waste. However, the AI designs colony ships full of cargo before this. If I obsolete the colony ship, it will create a new, correct one.
Further investigation.... I think this is a game bug. I checked and the AI is creating ships that still have Warnings. Now the problems comes about that it has a colony ship built, it tries to retrofit to the latest design and fails, but since it has a Colony (Rock) (even if its filled with cargo modules) it doesnt seem to want to build any more colony vessels.
Maybe it's seeing the "Prototype" module and thinking "I DO have a component that has the special ability "Colonize Planet - Rock". But when it goes to design it, it cant fit, so it dumps on a bunch of cargo modules and calls it a "budget colony ship".
Possible solutions.... tie the Colony Ship hull to said researches...remove the prototype module. I am not a modding export so someone else may have to figure something out.
