If you have multiple Lts on a city, can they each siege that city, thereby adding more than one siege token in a given week? Can they each roll to raze the city, thereby granting multiple rolls to raze the city in a given week?
If you were sieging a city and the Lt who had added the siege tokens leaves the area, but you still have another Lt on that city, do you keep all the siege tokens or are they lost because the original Lt left?
