I have 31 saved Minecraft worlds. All but one seem to be working fine. However, one of them crashed shortly after I start playing. I can usually run for about 20 to 30 seconds and then the game shuts completely down and I do not get a crash report. If I go back to the game it starts normally and I try to play and it kicks me out again.
The nature of this crash makes it so I cannot attach a screenshot or file to help resolve the issue.
