autouv,2 {badmatch,undefined}

Hello,

During work with UV map [MMB -> re-segment objects] for one of my projects I got:

Hank, this is an unexpected situation. It means like you have an edge information (the vertex id's) and when you try to look for them one isn't defined in your object.

Did you tried to use Clean before run this re-segment command?

I used your other problematic object and even in that malformed face I couldn't reproduce the problem.
