This sounds like a game crash; you should be able to find a crash report in .minecraft\crash-reports; copy and paste the contents of the most recent report into a spoiler; if there isn't one check for a file with a name like "hs_err_pid(number)" in the .minecraft folder (this is a JVM crash report); if there isn't one either get the latest log (or most recent one when the game crashed) from .minecraft\logs, or go to launcher settings and enable the game output window (if not enabled) and provide the contents when the game crashes.
somehow my pc didnt crash or anything (or even overheat wth [and i had bsl shaders on]) like wth
unfortunately cant post the image as "an unknown error has occurred"

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download.
TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
