Hey, so I had to replace my BIN folder because there was no other way to uninstall this mod that i didn't want. And so I did, and installed back the mods. I think I forgot to install some kinda village mod or so? I could run the game perfectly for about 10 seconds, then it crashes. I have FML, TMI, Better Furnaces, Damage Indicators, Backpacks, Bibliocraft, and Optifine. Here's the crash report:

Class net.minecraft.block.BlockMushroom
