Crash Rant

Don't you hate it when you crash when you are in the middle of something important?? That just happened to me. I hate that. I was just playing hunger games, then all of a sudden... BOOM, I CRASHED!!! It's also happened when I was role playing with my friends. (you know how that is.) We were walking over to like a pyrimid type thing that my friend built, and then BAM I CRASHED!!! And then we had to restart that whole part!!! I have optifine, but that just makes it worse!!!!! Post in the comments if something like this has happened to you. PEACE!!!
