So i've had this single player world i made for a couple of days now, no crashes , no problems. My dad wanted to join so i turned "Lan" on. While i was waiting for him my game randomly crashed (But didn't close the client) The music was bugging out and my screen was frozen as well as my whole pc. I turned it of with the power button. When i try to re log back into my wolrd it says "Loading terrain" and so on but crashes and closes the client just before it puts me in game. Anyone out there willing to help me ? I've got so far in thumcraft and don't wont to retstart my world for a 4th time. HERE is my crash report.

EDIT # 1 It appears lan might be breaking my wolrd as i tried to join, It said "Shutting down internal server" then "Server closed" and after that it crashes. So it might be lan OR a mod


EDIT # 2 Well i removed optifine for the time beeing and i got a diffrent error, turns out i have a corrupted chunk. Just delted my regions folder and manged to join back but with out my chests and stuff.. Lucky i have most of my good loot on me.
