Help Needed Keyframes

[Faolon12 1]

so i built a rig using parts of steve from the parts menu not the whole thing anyways i built using the parts menu a stig and parented all parts to the body

now when i go to import keyframes for my rig it crashes my game but not with other stigs is there something i have to do to make it compatible

also reason i had to use seperate parts is i have a custom head and i didnt have a body to put it on

also second thing i need help with is 

if you use the main body tab and summon is lets say steve or a skeleton is there a way to get rid of its head

Don't know how to fix that first thing but for your second problem: I'm pretty sure if you go down into the timelines and find the "Head" timeline you can delete it on its own.

si i cant delet it but what i did do was make it invisible so that also solves my first problem now i have a charecter that functions with any skin and can use keyframes

also i will make a video on this fix i found
