So the override isn't needed
Ah well, it may still be useful to people who also play on different servers besides this one.
And it did teach me how to make textures for Neverwinter Nights models, time well spend.
I've also noticed that familiars still use the old raven model, so it does have some use still.
And I have now also included an update for the wereraven in the same way as I did the raven.
