I am not sure if this should be directed here or at the Metallurgy thread, so I am posting it in both, just to be safe. The following error happens with just Forge and Metallurgy installed be it I install them manually or with MultiMC. I can start a game and I have played for a while, but I did not crash because of these errors, so I am guessing it might be something that does not matter. I would appreciate if anyone could tell me if these errors can be ignored.
