Mesh flips when using "generate" button

[erikari]

It either does this at the very beginning or when you close the mesh editing tool.
See http://esotericsoftware.com/forum/Bug-when-editing-the-mesh-in-version-3-6-43-9362 for a repro video.

Repro steps:

1. click on any attachment that isn't a mesh
2. check the Mesh thick to make it a mesh
3. edit mesh
4. click on "generate" (I clicked 3 times)
5. in my case, the image got flipped instantly, in the user's case, when he closed the dialog.
