During Save Hold the MANIFEST and .log files from the db folder do not unlock as they should and can not be copied.

I have tried this on 3 separate windows 10 systems on several different worlds including brand new worlds created by the server.

This means we cannot take a working backup of the world without completely shutting down the server.

I have checked permissions and this is not a permissions issue.
See screenshots attached.

This started happening since BDS 1.14.1.4
The Bug tracker will not let me choose this version as it is only showing 1.14.0.9

Very worrying! Requires URGENT attention.
