The Armature is not deforming meshes.
Exact steps for others to reproduce the error
First - I've added an armature and extruded 2 more bones.
Second - I've added a cilinder mesh.
Third - I've parented the mesh with the armature deform automatic weight.
Four - Its worked but was horrible because I didnt subdivided it.
Five - I've turn back some steps with ctrl Z and subdivided the cilinder, than the bug appear: the parent armature was not working animore. I've used the ctrl P, and nothing in the menu for armature deforming. Than I selected the object menu parent armature deform and it was there. I've activated it. But the pose mode has disappeared. I've only selected the armature and the pose mode was back. In the pose mode only the bones was moving, The mesh that was parented was not deforming and doing anything.
Help.
