The wolver animation is still broken. If they appear from the ground and then start to charge their attack, the ball model stays there.

This happens because there is no scale keyframe set for the ball model bone in the charge and attack animation, so the ball stays at the size that it last had(which is big/visible because wolvers use it for the teleport animation).
Something similar happens to the walking animation. The shield/weapon bone doesn't have a scale keyframe, so if you shield and then start walking, the shield stays that big until you stop walking. It also works with weapons, when you enter a level, switch weapons and start walking while switching the weapon will stay small until you stop.

It's ok if you don't understand the later part of this, it's more a information for the people that have done the 3d animations, so that they know what the bug is.
