There is an exploit where a crew can raise or lower an emissary flag without being near an outpost. They do this by voting with a minority vote at the outpost, then when they want to raise the flag, all they have to do is have one player leave the game and rejoin. So in effect, they can raise the reaper bones flag whenever they choose. This way they can avoid being marked on the map if they sink a ship they can raise the reaper flag on the spot.
If all votes are canceled when the ship sails away from the outpost then it wouldn't be possible to do this.
