Armature appears in edit mode but not pose/object mode The armature I made for my model doesn't seem to appear in pose mode nor object mode. I'm not sure if this is the result of creating an animation (the armature seems to have disappeared after I created a base animation and added edited versions of it by creating actions in the action editor). 

The armature appears just fine in edit mode, so I'm not sure what exactly is going on.

Does this have anything to do with deleting key frames?

Edit:
Thanks for all the suggestions! I still can't find a solution so I've uploaded the file. If anyone can help that'll be great.
The pose bones are hidden.



To selectively unhide the bones click the plus sign next to "Pose" and select the closed eyes.

To unhide all posed bones at once, select "Pose", hover over your mesh and press alt +  H.
