Bug description: As the mongoose builds, its animations show to be stuck in the same type of move.

several images and descriptions included in this link as proof

basically: the issue is that the animations repeat themselves.
They used to work just fine till the 7.2.5 update, but now instead of each move being original and having its own animation they're all the same as the first
