My Magic Island has been working for the past couple of days now and today I was playing fine and then I turned minecraft off to do some stuff and I tried to play on the world and it would't work. It would load onto the world but then the frame rate with be so bad it would be about 5-0 fps for no reason and I usually run 100- 120 fps on it. I decided to close it and try again but same thing it would let me log onto the world but i couldn't really do anything and now when I try it crashes on me every time here is my latest crash report.
