So when playing with both mods, despite having Base Quality setting > 0 , the condenser is always at 0 (having also tested without just that mod, it works fine)

Of course the issue is that K2 Spaced Out is somehow overriding this (because it works without), but I don't understand how that would be possible ? I don't know how the entities are added, but I would expect new entities & their settings be independent. I would appreciate if somebody could point me to the mod code I could change locally for myself to fix this

seems to work for me, note that you can only see the base quality when you place it down and not in factoriopedia.

@Quezler Sorry for the confusion, I did more thorough testing, and it appears it's the combination of mods that disables the base quality :
- Quality Condenser + K2SO => OK
- Quality Condenser + Moshine (planet mod with its dependencies) => OK
- Quality Condenser + Moshine + K2SO => NG (no base quality on the condenser)

Really weird behavior
