Hello everyone again, this time I present to you an open skyscraper in Los Santos. I could not remove the marker, but if you stand on it, you will still get there. But you can also enter the second door, nothing will change from this. (I.e. the Marker will not teleport you anywhere, you will pass through it). Installation and screenshots in the archive, everyone enjoy the game.
P.S If anyone knows how to remove markers, write to the PM please.
