all I did to trigger this bug was drink a potion of swiftness 2 and then pause to put on a video
as soon as I hit the escape the computer issued the blue screen of death
the blue screen of death said that I had run out of storage space, even though I still have more than half of my storage space unused

the chunks in the world I was in at the time no longer load and no interaction with the world is possible becides block breaking

I hope that this bug can be fixed in the future
and I also hope that the damage done to my map (which has been attatched) is reversable as i have spent many hours on single player building up this world.
