Split Screen player 2 controls player 1 avatar

beta 1.2.0.25 xbox one

We were playing split screen when the update initiated. Now when we load split screen, the player 2 (bottom) control cannot move their avatar; both controllers control player 1 (top screen). Friends within the same server (host) do not have the same issue. When the update initiated, the first time we joined back onto the server, a screen popped up saying "resources were regenerated, world crashed." Please Help!!!
