When my AE system needs to make an advanced machine casing, it gets stuck trying to make the last piece of advanced alloy, it can make the first one, and it even makes the mixed metal ingots to make the second one, but doesn't actually compress it. The crafting monitor doesn't say I'm missing anything. I am using advanced machines (singularity compressor). I am on 1.6.4. I don't think it's a problem with the singularity compressor since it can make the first advanced alloy just fine but it wont make the second one. I need help.
