Bodyslide custom body abdomen is wrong

[Shredder]

My custom body work well expect the abdomen part, somehow it works separate from the rest of the body. Maybe this is skeleton related, i dont know. I attach an image that shows how it looks.

Simply try'd reinstalling your skeleton? what skeleton are you even using? is it only occuring in this sneak animation? As you allready tought this looks to me like a weird belly node what body did you use to create your body in bodyslide?

Reinstaling the skeleton fixed it, thank you.
