Unreal Ports missing bones

I’ve been trying to port some of the characters from Mortal Kombat vs. DC, but I keep running into problems. It seems like whenever I try to load the model to scale it, bones keep disappearing. Usually, it’ll be the whole right leg or something similar that is missing. Has anyone else had this kind of problem?

Try to group the mesh and model together, then scale it. Has the added benefit of you being able to set the pivot of the group to 0 0 0
