Minecraft Forums

For some awkward reason, I could play Minecraft for an hour or two. But, then, I randomly crashed whilst placing down some quartz transport pipes. Now, every time I join my world, it crashed in two minutes.

I'm not the best with reading the MCR (Minecraft Crash Report), so, if anyone can help me find the problem, thanks!

Here is the report file":
