Thx Dogscoff, it's just as you said !
I checked the files, indeed the Mineral facilities have a "movement bonus" bogus feature and AI construction try to implant "Movement bonus" at first priority in its Mining Colonies !
So "proportionalization" of AI files could be a somewhat easy task, if we just had the list of "bogus" feature implemented and what they're used for.
PvK could provide that I suppose
