I want to use your mod in a pack and tried to edit the Custom Cobbleworks, that all products need energy.
Ingame it says, that it require 100 RF/t, but if there isn't any power provided it's still working. This only happens with the Tier 0 Cobbleworks. As soon as i upgrade it, it starts operating like intended.

Also i found another bug. The Cobbleworks generates doesn't always generate the choosen amount of resources.
Selecting 1 it generates 0 items.
Selecting 2 it generates 1 item.
Selecting 9 it generates 12 items.
And so on. I tested this with just a Hopper below the Cobbleworks.
Furthermore it looks like the resources aren't generated at once, because there is some kind of delay before all resources appear, after the first chunk of them appears instantly.
(Selected 9 and 9 Cobblestone are generated as soon as the progress meter reaches 100 and a few ticks later another 3 cobblestone are extracted from the Cobbleworks)

Cobbleworks: 2.4.1
Forge: 14.23.1.2559

Otherwise i really like the mod. So I hope this gets fixed soon or you can tell me what I'm doing wrong.

Got another problem I edit the tiers of the custom cobbleworks, but it still unlocks the new items like I didn't changed them.

Sorry for the late response, the email system was broken or something.

The custom block has had some issues for a while, and that combined with it being finals week means I don't really have a ton of time to work on it. I probably did something dumb with variable referencing, I'll look at it in a few minutes.

I published an update a few minutes ago, version 2.5.0 for any 1.12 game version. I think I fixed everything except the error where you were getting 12 cobblestone. I was able to replicate the bug, but it is so bizarre that I cannot figure out what is causing it right now.
