i am currently having problems with my character model. I have added a rig to him and his legs and arms work fine: except the head, the head does this:
The whole body was made of separate parts and i object->joined them. I also did some booleans for the chest part of the body where i union'd legs, arms and the head. I am kind of new to blender so any help is very appreaciated. Here is the file: https://www.mediafire.com/file/ydpb1sg1x2ojcr7/stylized_character.blend/file
