I had the idea of one being able to know the moon fases when choosing a day (setting) in the editor.

This means: Having the possibility to visualy know if the moon on that particular day of the month/in that year would be precise, instead of loading the mission to check it.

Sometimes at night, a full moon is good and all is needed, so, to sum up: In the edior, the player have the possibility of having the visual aid to know wich moon fase it is, on the mission chosen day.
