What led to this originally was that I had to reinstall my modded minecraft, in other words, basically I deleted all of the files inside my minecraft folder for curse except for the saves, which I moved to my desktop. I then re-installed all of the mods I had( or at least most of them) from memory and launched the game. I tried opening up a computer that was set up to simply receive a signal to open and close drawbridges. But after about 1 or two seconds of opening the computer my game would crash. After this I tried launching the game again, breaking the computer, and then placing it down and using it again. This time everything worked fine for about 10-15 minutes until it crashed again in the same way as described previously, resulting in this crash report: http://pastebin.com/mLgMH0gN
