Description

System Information
Operating system: Windows 10. 64 bits
Graphics card: Nvidia Geforce 1080, Nvidia Geforce 1070

Blender Version
Broken: blender-2.83-ce76e17584ee-windows64
Worked: N/A

Short description of error
I came across a weird bug. It's the second time in a row when I rig a character and create an armature and then move it around or rotate in edit mode and use UNDO several times and all of a sudden my armature disappears from the viewport. I can enter the edit mode, I can select it, but it's not there, It's not being rendered. It seems like the new undo sometimes just wipes some armature data.

Exact steps for others to reproduce the error
Sorry there are no exact steps to reproduce this bug as of yet. Just create a rig (also might use rigify as I did use it) and extensively move and rotate created bones around and use new UNDO.

Here's a corrupted blend file.

Thank you for looking into it. BTW, New UNDO IS AWESOME!

Forgot to mention that I enter XRAY mode quite often too. Almost 90 % of the time during bone placement I prefer to have XRAY mode to be turned on.

I can confirm that there is something strange about this file.
Although not visible, the bones are in this layer:

But it is strange that there is no indication that this layer has bones.
This is a bug, but it is important to know how you got in this state.
