Fitted Kemono Torso Alpha issue

[LilBunBun99]

I was online last night using the FireStorm viewer with no issues with this avatar. I updated the Viewer and as I logged in I notices the layer around the waist and upper leg was invisible. I reset the alpha layer multiple times with this avatar but it will not correct, Always going invisible as I redo it. I even used a different copy of the Fitted Torso and it was still doing it. It works perfectly fine with my other avatars but for some reason this one is not working properly. I took off the Fitted torso to be sure that was the issue, and I have no problems with the kemono avatar if it is not on. Does anyone know how I could fix this issue? I would rather know a fix for if this happens in the future than have to remake the avatar only to have this happen again.
