Metahuman Skinning Issues

I’m trying to animate metahumans in Maya but I keep running into skinning issues wit the thumb, at random angles it decides to invert itself and I have to key it back to a different angle for every single frame to make it not bug out.
Do I have an outdated version of the mesh or something?

Also is there a Manny or Quinn Maya rig anyone knows of?
I’m hoping that skinning would be better than the characters directly
