Hello,
the bug is still present for me.
- I did a complete cach cleaning (complete removal ov inventory/texture cache folder), relogged on empty sim, waited for inventory complete, relogged to my home.
- Skin change: all well.
- some minutes later: skin change: not ok:
In the viewer where I changed the skin, it only updated the upper body. (Cool VL Viewer 1.26.7 on Windows).
In a second viewer (fresh install) that I have open on my Mac, I don't see no change at all (Cool VL Viewer 1.26.7 on Mac).
Tried Firestorm (latest) on the Mac afterwards: sees the old skin on all 3 body sections, too.
Even a Rightclick-Avatar/More/Refresh on the Mac doesnt help to update the avatar running in the windows pc, so apparently the baked textures never hit the grid.

Log when I changed the skin:
The first skin change that worked, looks like this:
