Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Windows 8.1, rest not relevent.
Blender Version
Broken: 2.7.4
Short description of error
Exporting an object from a loaded .blend file (or without a save) will result in a lack of "vt"
Exact steps for others to reproduce the error
hoverbike.blend
With my blend file, export the object as an obj with default object exporter.
Look at the "player_atch" object, in the resulting .obj file, and you will notice a lack of "vt".
Then, close blender. Open blender. Import the .obj you exported, and export it in the same manner.
"vt" now exists!
Should also note, due to loops, importing and exporting reverses coordinate order. I'm doubt that affects anything, but worth mentioning.

4c1e066129Issue is actually with .obj importer, which adds (useless empty) lnor and/or UV layers to split part from .OBJ that have none… Fix incoming.
Changed status from 'Open' to: 'Resolved'
If I understand correctly Bastien, vt will no longer be inserted when exporting an imported .obj file?
Again, problem was not with exporting, but with importing (was generating UV layers when not needed).
