Short description of error
Hello there. I intentionally deleted the bones for teeth and tongues, while using the rigify add-on. I am using the human meta rig. I was not aware of this previously. Those bones were completely unnecessary, so I thought I would simply remove them. While trying to generate the rig, it is giving errors like those particular bones not found type of error. I cannot recover the file because this mistake was done in the earlier stage. So, it's lost. Besides that, for the missing teeth part, I recreated bones, renamed them, and parented to the spine, so the error was gone. But for the tongue, I added another bone, named it tongue, then extruded it, like making tongue.001 to tongue.003. I parented this tongue to face bones, same error. Has anybody ever faced this? I even tried transferring the constraints from a duplicate meta rig, did copying pasting things, nothing is working. Need help sorting this out, will be grateful. Thanks!

Clear rig animation data.

In fact, an error appears.
I was able to confirm the problem without having to model a humanoid mesh.

I confirmed the bug, now it is up to some developer or the author of the addon to fix the bug.

Thanks for the work. I found a solution hard way observing a fresh meta rig from scratch. The solution to this is long. I posted the solution on a video here:
