I started a Space Age Hard Mode run on lower resources and 10x research cost. Then half of a starting coal patch is gone before I researched Vulcanus cargo drop, while only using coal for plastic and rocket fuel necessary to launch science by rockets. By far the most punishing early planet.
Looked for a cause, and the simple coal liquefaction gives only 25 heavy oil for 10 coal. Advanced liquefaction gives only 20 heavy oil! (45 - 25 that it costs), 10 light and 5 gas. This feels pure evil and not well balanced.
I love it, but maybe still boost the stuff a bit especially the advanced coal liquefaction?
