Apparently so... I had originally took it to mean that Modo didn't support dealing with vertex normals at all until 301.

So that's great, it looks like I found the bug. Tomorrow I should be able to put out another new beta after checking over it carefully.

Thanks for your testing, and thanks to Rhumba for reporting this in this thread!
