I was playing minecraft and I was going with a lot of lag I left the minecraft and I go back and enter the world and waiting for me to appear or open chat what happens when one is sleeping and behind the map load to start playing and When it appears to me within a few seconds, it comes out of minecraft and I did not believe in another world because I was very advanced and I eliminated minecraft and re-downloaded it and worlds appeared that were from other versions and I go external and I cannot find my current world help please
