Added BBW to my mods folder to do a build I had in mind with lots of repetitious block placement. It did not seem to like that. I'll be redownloading to see if that fixes it, then downgrading a version if it doesn't. If the error persists...well, I'm in for a lot of RMB-holding.

Description: There was a severe problem during mod loading that has caused the game to fail

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Better Builder's Wands (betterbuilderswands)
Caused by: java.lang.NoSuchMethodError: net.minecraft.item.Item$ToolMaterial.getMaxUses()I
at portablejim.bbw.BetterBuildersWandsMod.preInit(BetterBuildersWandsMod.java:77)

Redownloading seems to have fixed the issue, will open a new issue referencing here if should return.
