I installed citadel 1.7,2 on my mc server but turns out it wasnt compatible so i rolled back to 1.7.0 and the Alex's mobs doesn't seem to be loading in

Error code that comes up on logs: [modloading-worker-3/ERROR] [net.minecraft.util.Util/]: No data fixer registered for "Animal"

I also got a notif saying to go back to 1.7.2 i feel like i may have uninstalled citadel incorrectly
