or just reintroduce them into the new factory branches eg the Yor could get 1 mining enhancement per collective tech.
Not possible currently with the way the XML tech requirements work... you'd have to make an entirely new chain of modules for each of the Yor, Iconians, and the Drengin/Korath, but then you would be able to build all these new modules
and the old ones (for a total of 4x whatever the current max Mining percentage is, at least for the Yor (since collective techs aren't tradeable), that is. 3x for everyone else, I think), assuming you trade for the techs that give them, of course.
This is strange because in all of my TA Beta games in which the Yor, Drengin and Korath are present, I've seen each of them build mining bases on galactic resource and asteroid bases. I can only assume they have the techs or are getting them from somewhere. If they are getting them from another AI, then they are able to consistently do so because I see those bases in every game.
Building a starbase on the resources doesn't have any tech requirment, just a constructor. However, the upgrade modules that increase the bonuses from these bases are only in the standard Industry techs. That's what he's talking about being missing.
