Qarl put out new Mesh Deformer code yesterday (2/13) about 3 PM. This release should handle the crumpling problem better. We will know as soon as someone gets the code into a viewer where we can use it.
To see the crumpling problem see: #SL Bare Feet.
so if you want to try
version 1.25 with the the Mesh Deformer 0.2
