Instead of having additional variants (i.e. having both Arcane Postosuchus and Postosuchus), my creatures are completely replaced. All Postosuchus are replaced with the Arcane, so on and so forth. Is this the intention of the mod, or is it an issue (either on my end or the mods')? I also have Pyria, so other creatures (i.e. Stegosaurus) are also replaced with their Arcane variants.
