Blender help

So!

I'm working on a model, and I don't remove ALL of the doubles on one mesh (because if I removed them I would have some issues).

So I export it, and import it again, and this happens:



The normal one is on left, the messed up is on right.

So what happens is that some of the vertices on UV layout randomly change places for no reason.

What causes this?

That happened to me with a few KH models too :/

A similar problem happened to me when I exported a model with a mesh part (can be really small) that has a different UV is joined with the other mesh.
You'll have to hunt it xD

Ya, I managed to get the method that need the least work.

So I separate the parts where didn't remove the doubles, and when I export, that problem occurs, but I have less work!
