Anno 2070, continuous game, Deep Ocean expansion is present (i.e. I have build functional food factories, I have the thermal power station available to me). I have over 5,000 researchers who have all their needs satisfied yet they are not advancing to the Genius level. I have no Geniuses at all. What am I missing?
Also, before someone points out that my question is a duplicate of Why won't my Researchers advance further in sandbox mode? let me tell you that it's not a duplicate. My question is about Anno 2070 with the Deep Ocean Expansion which does have a 3rd Tech tier, see Geniuses' Residences.
This is the tax rate, they are euphoric, but I can't seem to lower the tax rate further into the dark green, it just snaps back to where it is now.
All the needs say that they are 100% satisfied.
UPDATE: Something is definitely not right. I don't have access to the Immunity Drug Manufacturers either, even though I have more than enough Researchers to unlock it.
