Modeling with the mirror modifier (version 2.72), and my edges on the mirrored side keep disappearing (ref image below). It usually happens when I change the view. At first I thought it was something that I did. So I would dissolve the edges and vertices, then loop cut them back in. But as soon as I changed the view, some would be randomly missing.
Is this a version problem? Because this is a fresh install of 2.72 (previously using 2.70). I did a search for an issue, but found nothing.
Help??
