I just got back to the game after about a year break. Love it. I've always had the OPTIONS -->GAMEPLAY-->SHOW BUILDING NET REVENUE on, so you can directionally see which buildings are profitable.
I noticed the net revenue for metal mines (and sometimes quarries) are way too high. For instance, just started a map and aluminum is at $20. A high resourced aluminum tile will produce 2.0. So, I would expect the net revenue for aluminum to be $40. Instead the aluminum icon has $116. If I hover my mouse over the aluminum icon, I see HIGH ALUMINUM is $40 and ENERGY/POWER is -$4, which is correct, so again, I'd expect to see $40. So, why does the aluminum icon show $116?
During gameplay, I noticed this same issue with quarries sometimes, but never with other buildings..
