Noticed this making dawnstone; I'm running EmbersRekindled-1.2.jar and the Soot 1.0 that is calibrated to work with it, and when I feed 1 gold and 1 copper into the mixer centrifuge, I get 1 dawnstone out. JEI says that I should get 2 dawnstone.

can't reproduce

Yes, I believe wamc has it. This is almost certainly the same bug as #5.

Lemme try reproducing with a smaller pack than my kitchen sink.

I guess that's a duplicate of #5 and 1.2 doesn't contain this fix as far as I know...

oh huh, i thought i fixed that before 1.2

can't reproduce this in dev so probably fixed at some point or spooky bug
