Conflicts with the Aether Mod, Item 170-171; change them to 155 and 156
You can actually change them yourself :biggrin.gif:
Just go to your .minecraft folder, config folder, open up "net.minecraft.src.mod_MoreToMinecraft.cfg" And change what you need to :smile.gif: most ID's are self explanatory, but if you have any more questions let us know!
(or just me, since I'm the coder and have control over stuff like ID's XD)
