Suspicious change in Google Maps

This is an archaeological site that Serbs call Nebeske Stolice, located in the north of Kosovo in the Kopaonik mountains on the border with Serbia. It belongs to the 3rd-4th centuries with an intervention in the 5th-6th centuries, completely before the Slavic invasions, and the beam was destroyed approximately at the time when the Slavs came to Ballakan. Until 1-2 years ago, when I looked at this, they were in the territory of Kosovo, and a few meters further, they had the border with Serbia, while now it is in the territory of Serbia (photo 2). Does anyone know when and why this change happened? The Serbs use it as a holy place, although it was most likely destroyed by them during the floods in the 6th-7th century.
