I don't know exactly what happened, I was enderpearling around and I received a crash report. I figured that I could at least report it, even if it's not important. I included a crash report in the attachment
Environment
It was on a Multiplayer server, so if that has anything to do with it. Core i3, 4gb RAM is my client. Not the best graphics, but it still runs on Normal on the snapshot surprisingly.
