[PvK]

I don't think the AI will freak out, depending on your definition of the term. It should just go about its usual business, although I haven't tested hidden warp points or sphere worlds. I would expect it to be completely ignorant of planets with abandoned facilities. I don't know if the AI respects hidden warp point visibility or not.

The only thing that might throw the AI off a little is if you give it tech that it isn't programmed to use well, but that could be adjusted.

You could start in 2.1 and upgradee to 2.1 without problems, I think, though I am still meaning to release 2.2 tonight.
