I have a mesh and I have an armature that I placed within the mesh. I select the mesh, I select the armature whilst holding shift, then I do a Ctrl+P to attach the armature. I click Armature Deform with Automatic Weights, and suddenly my entire mesh decides it needs to be somewhere else and moves to some new location--the bones are no longer within as they remain where they were. What gives? Why is my mesh moving away from the bones?
