[AVAILABLE][SERVER][INFO] Altering Melting Recipe(s) for <liquid:aluminum> * 288

The recipe appears to being added fine, at least on our side.

Try crafting the recipe? it may be an issue with it not showing in JEI.

If that doesn't work, I would say report to Tinkers Construct, but I doubt they could help since 1.12 is old at this point.

Found the issue... It was the shadows of greg's integration with tinkers.
