There is one world, where second player is unable to access. We used to play on playstation 4  offline multiplayer (splitscreen).

For the first player the world is still normally accessable. But when the second player wants to access, it splits the screen as usual but the second player then is stuck on the loading screen.  For the first player everything ist normal. The avatar of the second player also appears in the world, but does not react to the Environment.

this problem is only with one specific world. As we tried another one, everything works just normal.
