Note this is more for K2+SE than just pure K2. Would it possible to make the methane from adamo carbon and the methane from space exploration the same item? Space Exploration's methane comes from methane ice in space. The issue is due to the two different internal names used for the items.

Will look into it when adame carbon updates to 1.1 and i have time and motivation, since i did this mod mostly for myself and my friends

No worries I ended up removing adame carbon so I can update to 1.1 and it wasn't much of a loss.
