Hi
@DeathRipper12125, welcome to the forums.
Sorry to hear that you're having trouble with opening your favorite world in multiplayer. I don't recall hearing anything similar from other players.
Are you trying to open the world with the same character? What happens if you try to open it (in multiplayer) with a brand new character?
In any case, I suggest that you send in this information straight to Pipeworks (the console developers). Include as much detail as you can. This is the fastest way to guarantee that they see your issue:

You can also send in your character and worlds. This way they can see firsthand what you're talking about and it may help them find a fix for it sooner:
SEND US A COPY OF YOUR SAVE DATA
If you send in a bug report using the url I linked above, you probably won't hear back from them, they aren't able to answer each bug report individually, but be assured that they look through every bug report that comes through.
