You know what? I will go check, maybe somewhere in my location there is a forth tile. I removed the three I could see, but as two players now had four left, maybe somewhere there is another one in my game.
Also I can check if the last tile finder does anything when „624/624“ is reached already, but tiles are left. Should have tried that with the visible three…
Edit: Forget the LTF, as soon as the location is marked „cleared“ it doesn’t appear on the screen, you can’t use it.
Edit 2: I couldn’t find another tile.
