I woud like to know if you have probleme with the option "Change material thickness" when you creat your TWD file?
For myshelf I always had problem with that. Like this morning I did change my material thickness and my nest wasn't ok... there was parts missing or there was more parts that it should be. So I would like to know if I am the only personne who have that problem.

When I tested your files in V5.2, I didn't get any error messages like you were talking about. It seem to work fine, there was no double parts or missing parts.
