mesh partially changes to invisible when temp_worn

[Raena Parx]

This is the weirdest thing. I have a mesh syringe with a tube atttached (flex).  It rezzes from a rezzer then waits to be worn. Once avatar touches it to attach it, one part of the syringe turns invisible. When I went to right click it to go into edit mode, I had'nt even gone into edit mode yet---just the right click made it visible.  Any ideas?  Here's a picture.
