I went through my portal to the nether, the game was super laggy (which isn't unusual given my video settings) as I walked away from the portal, I saw a ghast fireball (because a ghast kept shooting at me) suspended in space spazzing out (it was supposed to be headed towards me, but it kept moving forward a tiny bit then teleporting back a little bit). The game froze for a few seconds and then crashed.

Now whenever I try to open the save I see that I'm back in the portal (even though I had walked away from it before it crashed the first time) for a second and then Minecraft crashes. So basically as soon as I try to open my save the game crashes, so I think something generated/happened in my save that causes minecraft to crash whenever it tries to load. My save is 32 megabytes which is larger than the 10 megabyte attachment limit, otherwise I'd give it to you so that you could replicate the bug yourself. Is there any other way for me to send it to you?
