Rigs not properly loading into Mixamo
I see 2 problems that have occurred over the past few days.
- When uploading a Roblox Character Rig to add to Mixamo, it adds a block/brick at the feet of the character.

- Previous, unchanged, Rigs also do the same ^
This is preventing me from getting past the Auto-Rigger.
What has been changed recently that has done this and what can I do to prevent this?
