I’ll add to this, too. My character is also experiencing this problem. However, after the reset today ( April 8 )my character’s thigh and pelvis are also now metallic.
Update: My character no longer has metallic parts. However, my meck is now strange and clippy looking. Like the head floats above it insead of being on it. It is easy enough to hide with armor, however. One step closer to being back to normal!
