Hair Doesn't follow Ragdoll

Video

Been struggling to get my art assets into UE4 for the past few days, been one issue after another. I don’t know what the issue is with my skeleton but every time I generate a physics asset or create one myself it melts into a soup and falls through the floor with the hair floating above. Anyone know what’s going on here? It looks about the same as the vid no matter what I do

Hair won’t connect to any of the bones and arm joins refuse to connect to each other.
