OK, that's why then. I probably tested it back 5 years ago when the game was new, found it didn't stack, and totally missed the later change.

PvK, so what about those you list above? If I have a Robotics Factory III on my mineral-producing planet, then later build a System Mineral Scanner III, do both those bonuses stack?

Would Mineral Scanner III stack with System Mineral Scanner III? Enquiring minds want to know!
