Strange physics simulation on Skeletal Mesh

Hi,

I have a skeletal mesh that I made myself that I’m trying to use as a physically simulated object in Unreal. I made it in Maya, everything looks ok on export. I bring it into Unreal, everything still looks fine. When I simulate physics on the mesh, some of the joints snap together and become concentric. Here’s a video of the behavior: - YouTube

Here are screenshots of my settings on the mesh’s physics asset:

Any idea what’s causing this behavior? How I can fix it? Thanks!

Update: This seems to stem from when you select multiple constraints at once in the constraint view and rotate them using the rotate tool all at once. I selected four different constraints and rotated them all 45 degrees or so and then this behavior started occurring. If I rotated each one individually, this behavior did not occur.
