I tried to use a .blend file that is 1 year old. I wanted to use the mesh to animate something, but I noticed I used EdgeSplit instead of auto-smoothing a year ago. Here is the problem, when I "remove doubles" and turn on auto-smooth nothing happens. Is the file corrupted, does Blender doesn't support older .blend files? Please help, I literally sat 3 hours here pressing random buttons like a monkey and nothing seems to work <3
