Guess, it's more than a weird issue, but I have to report it:

If you have Metallurgy installed (mine is 3.3.2) and chests disabled (B:ChestEnabled=true in \config\Metallurgy3\MetallurgyMachines.cfg), RefinedRelocation will crash at starting Minecraft:

If you enable the chests from Metallurgy3, the game will start without a single problem.

Hope, my report can help you to figure the problem out. I guess, you're trying to hook your into Metallurgy3 but since chests won't get loaded by config, Forge guesses that there has to be something to hook in and crashes, because there is nothing to :).

Maybe you could do an option in your config of RR to disable the implementation of RR into Metallurgy. I think, this would be the fastest option, wouldn't it?
