What does the "+ 1 use for each character resting" in "when you get a few hours of rest and use 1 Supplies + 1 use for each character resting" mean? Do you spend a use for each other character resting? Or, do they spend a use of their own supplies? I sort of figured it was just the character spending a use of their own supplies and getting all of their Resource back and then the other characters can choose to do the same from their own supplies or from an allies.
