Something that came up when I was playing this game for the first time tonight (loving it so far :D ), and wasn't entirely certain from reading the rules:
If the Imperial player freezes a leader in carbonite, he/she replaces the "Captured Leader" ring with the "Carbonite" ring. Does this mean that the Imperial player can have a 2nd Rebel leader captured at the same time, with a different ring on each one? The only thing I can find in the rules says that when a 2nd leader is captured, the "Captured Leader" ring is taken off the 1st and put on the 2nd thus freeing the 1st.
