Every time I load a world, I received this crash report as soon as the loading screen is over. I'm pretty sure that this is the mod that causes the crash. This is the crash text file. I just wanna play this mod it seems really cool.

After I've tested some more, I have found that the result of this crash was optifine believe it or not. I've installed another version of optifine and no longer receiving this crash report.
