Hi, thanks for the report. I can confirm on master.

This was working on previous version. Will bisect

Not bisected but I suspect this as a culprit commit 3b6ee8cee7

(Setting this to high priority since this is a regression)

hello i am having the same issues in blender 3.0 ...Renaming bones breaks the rig and sometimes the weight painting is gone, when i move bones the mesh doesnt move, it seems that blender have troubles to refresh the changes of the renamed bone and having problems to rename the vertext groups accordingly....i had to go in vertex group and click several times then go back...then suddenly after a few minutes then blender decided to reflect the changes...then when i move the bones, then the mesh moves again. But to have to this with all my models is just a waste of time to try to force blender to do the refresh.
But to my disappointment when i exported the rig to fbx, there is was big hole in the eyes of my mesh...
what is the solution to this problem, do we need to downgrade blender ? this 3.0 is not ready i think

also i want to add that since blender 2.79 the fbx exporter was never working, so i had to buy a plugin called better fbx on blender market...i never had any problem to export my fbx but now i see that blender is causing issues after i rename the bone of my mesh

kindly fix this, this is very annoying
