If you are writing your own Scenario, create a gathering preset which has the checkbox ticked and use it in your scenario with gatherPreset(name)
If the Scenario comes with a gathering preset, you need to check the checkbox on this preset and overwrite it in the gathering tab.
If the Scenario doesn’t come with one, you can check the checkbox in the gathering tab and it should be used automatically, if there are no gathering nodes near you.
But you should think about changing other Scenarios compass settings. Normally a Scenario is designed in a way that it either needs the compass/truth or not. Some Scenarios uses grids, which have “beacons” acting as the compass without using the skill, because overusing it might attract attention from other players.
