I check the team-thingy. Worked for a simple object in a simple scene.
Hope, it's rock solid :-)
Sorry mate, I can't be any more help in regards to team files as it's not something I use.
From my understanding, you can import team files into your main/master ved & they will then update the master ved with whatever they have edited/added/removed while leaving the rest of the master ved untouched - I might be wrong though...
