Crashes Repeatedly.

I was farming some sugarcane which i have had NO problem doing in the past besides a little lag from the snapshots. Anyways, the game crashed and now when i try and open my survival world again it crashes every single time. This really sucks. I do not know if this is technically a "Bug" but this just started happening when i updated to the 14w28a snapshot. When i go back to 14w27b it doesn't crash. So for now i shall stay on 14w27b
