HoMM VII Haven Units – Haven faction units from the seventh installment of Heroes of Might and Magic.

Here's a suggestion on how to "fix" the movement animation for creatures. Set any standard creature that can walk as the main model, and make it invisible. Attach the model of a pikeman or crossbowman from Heroes of Might and Magic VII as an effect, and make it walk. The main, invisible model will be responsible for the movement, while the effect will animate the legs.
