From September, rentals for ships will be based on usage instead of time. The current system where a ship rental lasts 7 days will be changed to 10 uses per rental. This means your rental won't go unused if you happen to not be able to play for a few days during those 7 days. Note that we are in Back to Beta mode so this could potentially change again! Let us know what you think in our #Suggestions channel on Discord.
