If you are being reinforced by someone in the alliance (mostly to help there troop upkeep) and they leave the alliance (for two days or so is the timeline).
And you get attacked by another alliance - will the old alliance members troops still defend your city or will they attack you as well?
So say i'm in alliance (a) -- and my alliance member briefly goes to alliance (b) -- and someone else from alliance (c) attacks me. Will i be attacked or not by my alliance members troops while he is briefly in another alliance?
