I opened the game console in-game at last boss and i read a line there saying [flow] Animations:Boneinfo: Cannot find bone 'Bip01 Head' in character 0 of entity 'AB3_AlienBoss_entity'

Having a little experience with 3D programs i guess thats the file that needed to animate the 3D objects you create. Why isn't there then?

I tried reinstalling the game even repaired it with origin and didn't work with either one.

Some help from the support of Crytek would be nice to assist here or some patch coming soon to fix this, cause i seen many ppl have the same problem like me.
