What problem does this solve? This would just change the visuals, without affecting anything else. Though, I suppose with the new 3D membrane that may be too expensive to regenerate, this would be an option to solve that, without moving to the model where all your organelles duplicate only after you press the editor button.
Is there a non-gameplay reason why cellular processes become more effective as the cell expands (like some kind of scientific basis for this feature)?
Btw I can’t remember where this was, but another idea (besides the one that organelles only duplicate when you go to the editor, so it is only like an animation and doesn’t impact gameplay), is that the player can select the order the organelles duplicate in the editor, to fix the problem where your ATP producing organelles divide last and cause problems.
