Well, as I said in my other thread, I have gone back to an earlier base mesh version of my human model. So far, it was totally worth it, except for one problem. For some reason, when I was extruding the neck, some of the edges/vertices did not stay together (even though I have the keep new faces planar and together options checked). If you download the file, and I would love it if you could, and turn on border edges, you will see what I am talking about by the neck. If anyone could fix this or tell me how to fix it, I would greatly praise you, as I could finally get back to modelling as per normal.

Thanks in advance.
