I had a similar issue once. replaced blocks with stone to fix the issue for me.
you can also try using mcedit to modify the world "offline". you problem seems to be at: (618,0,-2426)

I'm not a genius but it appears to be caused my liquid metal from tinkers construct. Possibly a corrupted block, you could use world edit and //regen the block/s in that area. If you can't login in /minecraft/world/players and delete your player.dat which will move you to the world spawn and clear your inventory so you can move around.
