Does System Computer Complex...

Yes, it's a faint memory which someone reminded me about semi-recently. I thought it was around the Gold release.

I think I was probably confusing it with the change in 1.89 to the values of some of the levels:
2. Changed - Mineral Scanner I, II, III have had their modifiers increased to 15%, 30%, 45%.
3. Changed - Hybrid Eco - Farms I, II, III have had their modifiers increased to 15%, 30%, 45%.
4. Changed - Radioactives Collider I, II, III have had their modifiers increased to 15%, 30%, 45%.
5. Changed - System Mineral Scanner I, II, III have had their modifiers increased to 15%, 30%, 45%.
6. Changed - System Eco - Farms I, II, III have had their modifiers increased to 15%, 30%, 45%.
7. Changed - System Radioactives Collider I, II, III have had their modifiers increased to 15%, 30%, 45%.

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!

Robotoid won't stack with a Mineral Scanner because they use the same ability - the higher value would be used. The planet-wide ability does stack with the system-wide ability as Kwok mentioned.
