You need to use an existing xenogerm, but you cannot compile any xenogerm with more than -5 metabolic efficiency. This means, best case, you are always wasting at least 2 metabolic efficiency wince nothing above +5 counts. But I don't WANT my pawn to never eat, I want to use that + 12 to jam pack more wild ♥♥♥♥ into the sleeve and make some Frankenstein BS. I previously used the Gene Fabricator mod to create the legendary sleeve quality gene and add it in the xenogerm editor stage, just to allow me to circumvent that, but it seems that this gene no longer shows up on the xenogerm editor.

Is not being able to use that +12 fully intended behavior?
