Co-op

Me and my partner have been playing dont starve together with each other through split screen local play. We recently tried to set up a world to play for when we're not together but no matter what we do or what settings we mess with it won't let us join the other persons world. It will show up and say connecting but just send us back to the title screen or give an error message. We tried joining local worlds and it works just fine but we cannot get our worlds to work.
