I was fighting Skeletron Prime with my friend on Hardmode when he died. On his screen it said that I had left the world and on mine it showed him frozen when he died. I kept fighting the boss, who had despawned on his screen and successfully defeated him (first try! >u< ), but he didn't drop anything. Does anyone know why, or has this happened to you?

Note- We were both playing on iPad (iOS)
