The Auto Workbench doesn't Lapislazuli-blocks, others like Coal-blocks or Redstone-blocks work.

works just fine for me, most another mod has removed the recipe (crafttweaker/modtweaker/...) also what BC version?

BC Version is 7.99.4, have removed all mods from the mods Folder, still doesn't work.

Also updating to the newest forge version doesn't do anything.

we are still unable to reproduce this ourselfs with 7.99.4. could you reproduce this once more and provide the logs from that sessions? maybe those hold a clue as to what's going on

I can reproduce this if I change something about the lapis lazuli item, such as rename it in an anvil. Can you turn on advanced tooltips (F3 + H) and hover over the lapis in both the autoworkbench and the item in your inventory to see if it has something like NBT: 2 tag(s)?

Not sure which log you mean...

FML Client Log.zip
maybe this is the correct one.

ok looking at the logs your forge version is pretty old, could you update to the recomended forge build for 1.11.2 (1.11.2 - 13.20.1.2386) ?

done.

so updating forge didn't fix it?

nope

yeah i realy have no idea atm then as to what is causing this

I will reinstall Minecraft as soon as i have better Internet Connection. Maybe that could fix it.

Also when i start Minecraft without any mods it has the same ID.

if that's the exact stack you used to set the recipe and try to craft it should work (and it works in all our tests)

Closing as we are still unable to reproduce this, the only explanation at this point would be that another mod is messing with the recipe in some very weird way
