wait... problem solved,i had to remove the resource packs from the .minecraft folder
Also Neko,it isn't resource packs... that's ruled out
REMOVED RESOURCE PACKS
– IT DID NOTHING
wait,i found the crash report...
[media]
added the log,it won't give me the crash report,clicking the "view crash report" thing doesn't work at all,i click it and it does nothing.
I had the same experience,it happens if you try to load up any superflat world,mostlikely because of the water block being removed,and the water level being unset in all presets,to my knowledge.
