Hello,
is it possible that Άγιος Χριστόφορος ( https://www.openstreetmap.org/#map=16/40.9702/24.1464 ), a small village to the north of Νικήσιανη is misplaced or wrongly associated with Άγιος Χριστόφορος here: https://www.openstreetmap.org/#map=16/41.0421/23.7748?
I found a name:mk=Оравиште tag on Άγιος Χριστόφορος #1 which is definitely the old Bulgarian name of Άγιος Χριστόφορος #2.
Best regards,
