When I try to freeze a mob, my minecraft crashes with the following error message, "The game crashed whilst rendering entity in world
Error: net.minecraftforge.fml.relauncher.ReflectionHelper$UnableToFindFieldException: java.lang.NoSuchFieldException: layerRenderers." I am doing this in a singleplayer superflat world using the following other mods: Advanced Swords, Biomes o Plenty (not in a BOP world though), Voidcraft, Just Enough Items, More Commands, OptiFine HD, and Tam Modized.
