I hope I articulated this correctly. This is also really embarrassing, you can kinda tell what the picture is of. Anyway, I was in edit mode, grabbed a few faces and moved them outward, jutting out of the mesh. Sometime later, I don't even recall when this happened, but it was just went all concave as you see in the picture and I'm unable to restore the previous / original shape. Un-subdividing works, limited dissolve works, but it returns back to the pushed in state when I switch back to object mode.
Any advice? Any magical restore mesh button? Or some way to preserve edit mode alterations? I appreciate your time and consideration.
