Thought I removed that model from the package, sorry yeah it didn't work properly so I didn't intend for it to be included anymore. The issue with the feet was a weird collider issue I couldn't fix without using Acidbubbles collider editor where a lower leg morph extended too far below the feet. As for any other issues, I don't plan on updating the futa model right now so I'm afraid I can't help with that.
Still my favorite looks on vam, which is saying something!! The new thicc version gives me an error when loading her scene saying it couldn't find the morph though!
