Issue with FG 1.61 conversions

[Trykz]

Pretty sure this is something I'm doing wrong, but I've never seen anything like this before, so figured I'd ask.

 

This is a pretty basic mashup I created in outfit studio using a couple of different clothing nifs. As you can see, something isn't quite right here:

 

 

This only happens to the left leg, regardless of any outfit nifs I use. Everything else looks fine. So what am I doing wrong?

 

TIA,

At first I thought I was doing something wrong. Now I'm not so sure.....

 

here is the same mashup converted to 1.45:

 

 

No issues whatsoever..... physics work fine, and everything conforms perfectly.

 

I'm not sure what *errors* 1.61 was meant to fix, but it seems it's actually created new ones.
