I can't clear 18 tiles from the Olympic Stadium in Greek Father at the start of the location because the 4 people are standing in the way and don't move or disappear. I have finished the rest of the location. Is there something that I can do to make them move?
I see, i looked at mine and they are not in my way.
You will need to Contact SUPPORT
Look half way down for support option.
On your game screen, choose the Settings cog (Mobile, upper left corner; PC, upper right corner)
If you're on an iOS device, try the SUPPORT link, but if you don't see any categories below the search box, then you'll need to email them.
Seems dragging the stone a bit right from this screenshot stone would trigger them to move
