Description
Ran into this one where a Region had been on a server but after a bunch of crashing and meddling in Master Proc WALs, any attempt at unassign has the procedure fail (see below) and then report the region as STUCK.
I broke the lock w/ new hbck2 tooling and then tried to offline again but same thing happened. Bug. Fix.
