I really don't want DI parts to be unlockable in the Creature Stage, it greatly hinders my progress in getting parts. While uninstalling DI 9.R and re-installing the wanted features (Half-black UI, Genetic Modifier, Infinite Complexity, DI Audio and Text) works, that doesn't come without a LOT of crashes.
Overall I feel it would be a lot easier to simply disable the parts "pollinating" in the creature stage as a whole, so that only the Core Spore and C&C parts are unlockable
