When trying to load the new snap shot everything loads in perfectly if i were to try and play myself, but if i wanted to play with my boyfriend we seem to not be able to do that with the new snapshot. We tried seeing if it was one of our computers but its not because regular minecraft is working fine for us if we do it without the new snap shot on. When he opens the world to LAN and i join in and says that i joined the game on his screen but mine doesnt load and then the game crashes. We havent been able to find anything about not being able to play multiplayer with a LAN world with the new update to see if its an issue that alot of other people are having. I dont know if maybe because the game has something that doesnt allow LAN games to work or what but we have never had an issue with a LAN world doing snap shot before this one, and playing on the latest update not on snap shot works perfectly fine for us.
