Reported with a Logger32 export: the record said <DXCC:3>151 and OpsLog stored 54. cty.dat answers one question — where is this callsign TODAY — and that is the wrong question for a log. R1MVI was Malyj Vysotskij Island, entity 151, until the ARRL deleted it in 2012; the same call resolves to European Russia today. Forcing the lookup onto a 2004 contact therefore destroys a credit that can NEVER be worked again, because the place no longer counts. So the ADIF's number wins whenever it names a deleted entity, and nothing is corrected on those records at all — the country name and the zones of a deleted entity are equally beyond what a present-day prefix table knows. The list is the ADIF specification's own enumeration, sixty-odd entities that only change when the ARRL deletes another one. The guard sits in the forced path, so it also covers the grid's 'Update from cty.dat' on a selection — the other way an operator could have lost the same credits, one right-click at a time.
