Thanks for the nice mission.
bugs I found after resuming from a saved game (my gfx driver crashed):
factories lose ability to build anything
if you destruct factories via options they work again, even for AI
after destruct and build new factories I end up having two of them each, not sure if AI workers build a new one after destruction or if the build command builds two of them
not sure about the above mentioned "can't capture towns" after save game load
