From what I can tell, this only takes the last loaded recipe for a certain fluid - with Maraxsis installed, this moves atmosphere barrelling to the Liquid atmopshere research, making Maraxsis impossible as you need atmosphere in order to run domes to make the science, and you can't make atmosphere on Maraxsis itself
The single line ["maraxsis-atmosphere"] = "maraxsis-glassworking", in exceptions.lua will fix this as it will move it back to the tech that unlocks atmosphere collection

Thanks for reporting, I'll fix it in a second thy way you described (I have not played Maraxsis so I trust you).

Maybe I'll follow with a proper implementation of graph and recipe walk to determine the tech which unlocks the fluid for player.

quickfix 2.0.1 released, looks OK on my side.
