Vertices Disappeared I've created a UV Sphere and started modifying the vertices via the various editing tools. When I finished editing and went back into Edit mode, I noticed that some of the vertices have disappeared.
As you can see from the image, the center of the sphere appears to have no vertices.


Can anyone explain in what scenario this would occur?
Thanks for any help provided.
You could triangulate the face, poke it, or merge the vertices together. Also if you want the shape to be rounder, use the loop tools addon to make it a circle.
