Make it possible for players to choose an area in kms/miles around the station for spawning missions, make the max option as the way it is atm and make it possible to reduce it.
With this, missions will spawn inside the area configured in that station.
This would help avoid missions spawning in water and also will avoid missions to spawn on the other side of the river (making you have to wait 8+ minutes to cross the bridge and reach the mission...).
It would also help those that play realistic by making it possible to make missions spawn inside the station coverage area.
Example <- just like how it is here, but for each station.
