I looked into the Kingdom of Mentalak.
Today or tomorrow, I will manually wipe out the next layer which is the database records related to all the items on the map of this country.
All names and locations of items will be wiped out too.
The following month run should then rebuild these records, based on the source, which is the country database with all numbers of items and their types.
This is a more radical solution and as I know the underlying structures, it should resolve the problem.
In case it does so, we will automate this action and extend it to all C3 countries on TA.
This is radical but has no other consequences for the countries.
At this point, we have reasons to believe that there is no more to this problem than the false records that currently describe these items.
