Hey guys, back with another question.
Sometimes when i'm uv mapping, when I unfold a shell the UV splits up into parts and going back to the object there are several vertices where there was only one before.


Second image is after unfolding.
I've tried the following:
Deleting history and freezing transformations before unfolding.
Deleting UV's, history and freezing transformations before unfolding.
This isn't the first time this happens, I checked for poor topology but there doesn't seem to be anything wrong with it.

For future reference, is there anything else that could cause this?
