Recently I tried to enter the survival dimension, but rather than going right in or getting the bad header error, I was teleported to a completely random place. I was invisible, in hell, unable to move or take out my map, the chat was all white, and commands did not do anything (which i assume means no plugins were enabled), and I was also in singleplayer, as nobody would respond to any of my messages, and I couldnt see anyone elses messages. When I hit Save and exit, instead of bringing me to the title screen, my game crashed.
