In my game that I started fresh for the Oil Upgrade, I have a constant warning about not enough Oxygen generation. I am not thinking the warning is correct, although the report shows massive more gas lost than generated - at the same time, my coloiny has only 8 dupes and 5 Algae Deoxidyzers running all around the cycle. The pressure in the colony is in the green zone (bright blue on oxygen overlay), and was so for most of the 69 cycles so far.
