I've reported this before, and it was closed without word. Anytime when I use the psi deobf jar in a dev environment, I get this error: net.minecraftforge.fml.common.LoaderException: java.lang.NoSuchMethodError: vazkii.psi.common.block.BlockCADAssembler.setStepSound(Lnet/minecraft/block/SoundType;)Lnet/minecraft/block/Block;

If it was closed without word, that most likely means we're either not fixing it, or it's not our problem

There's no point in even having a developer jar if it's broken and not going to be fixed then. Was really hoping on adding some psi compat ;(

update forge

Actually Psi needs to update. We're 9 versions ahead

Then downgrade forge

Cant, other mods like JEI need newer forge.

Yeah unfortunately vaz has exams right now, so it'll have to wait a bit
