Hi, I was modifying my redpower frame quarry, and as soon as I placed a frame, minecraft crashed, and crashes as soon as I load the world up. I can see my inventory for about 2 seconds upon loading and the spot where the frames were is now an invisible item with the number 5 (meaning I have 5 of them) on it in my hot bar. Here is the crash report I think. Any help is GREATLY appreciated!
