Issue with moving head after modifying the mesh

[testuser]

Hello, 

I have a question about an issue i get, when I modify the wrestlers mesh and move the vertices of the wrestlers head too much.

The result is, that the head moves periodically up and down and seems to switch between two different states. Does this has to do with the eye blinking animation and are the vertices under the influence of that animation ? And how can I avoid this ?

Solved,

To replace one wrestlers head with the head of another wrestler (also male to female or vice versa), the different animation states (morphs, blend shapes) have to be replaced, too. I first did not know this and the result was the described head movement, because the head is animated in game (blinking animation).
