Cubium has alternative recipe for all the science (ingredients + cube = x2 science pack). Its like the primary reward for that planet, problem is it has only the original recipe so make this mod obsolete the moment you get that research.
Maybe its a little weird to ask for this because the mod idea is being "harder" while cubium give you a x2 but it adds even more complexity so I think doesn't betray the spirit of the mod.

Hi,
Indeed it's a good idea.

I'll see how to do that :)

That’s done with the new version !
I’ve also taken the opportunity to make Cubium compatible with my Aquilo Overhaul.
