Nuclearcraft Alloy Furnace 1 iron + 2 coal = 1 steel recipe doesn't work (SS has 10 + 20 but i've also tried just 1+2)

Could you try without upgrades please? :)

same :(

Tried a break and replace after, same result.

Hmm.. can your Alloy Furnace make other things?

Yep. Right after I found this out I swapped in the Graphite + Iron = Steel recipe and it works just fine.

Cool, thanks, I'll investigate :)

Sorry but i didnt see that recipe at all with coal at all.

@NillerMedDild, Note that shortly after this I restarted my server because i was encountering the "0 vis available" thing in Thaumcraft and it occurred to me to re-test this recipe ... and it works fine after the restart.

FWIW: my server is essentially private w/4GB, just me on it, built-in install of E2E(v1.8.1a) on Bisect and reboots nigthly. It had been up about 10-12 hours when i encountered this and i'd played probably 4-5 of those.

Alright, thanks for the follow-up, not much I can do about that sadly :/
