Creatures Caves

Hey guys, lately I've run into a problem I can't seem to fix. I originally had the Pearlescent Grendels installed to my version of GOG Exodus (WIN10), before realizing they were the same slot for a breed I want more; the Plant Norns. I removed the corresponding egg agent for the Pearlescent Grendels, but for whatever reason the Plant Norn sprites won't appear. I just see the Pearls. I have tried manually overwriting the body data and sprite files, uninstalling and reinstalling both DS and C3 several times, as well as manually wiping all my agent/etc. folders and repairing the installation through the GOG launcher. Even when all I have installed to a fresh version of Exodus is Plant Norns and C1toDS (for the offline button), I still only see Grendels for every type of Plant Norn. I've never been too keen with sprite errors... Is there a way to force the Plant Norn sprites to override the Grendels?
