Bats Animation Malfunction

Was trying to build a supermarket in the new snapshot, and this bat decided to fly upside-down. I have a feeling it is because while updating the Vex model and flying animations  (assuming bats and vex used the same animations) either the Bat's flying animation got deleted or it got corrupted somehow.

Bat Animation Glitched - is a link to the youtube video showing the glitch in my world.
