Did you end up testing?

In any case, this is not entirely a bug, mostly there is not a good way to migrate. For a short time during 1.18 before amethyst bronze existed, I merged bronze and tinkers bronze, so tinkers bronze migrated to bronze. When amethyst bronze was added, bronze was made conditional again, but its still the best target for tinkers bronze.

What I might do is migrate tinkers bronze conditionally to either bronze, or if bronze does not exist to some other material to remove the error. JSON syntax already supports that, so it will ensure if you play with bronze, you get the more comparable material, but if you play without your tool is at least not broken.

Tested with Tinker+Mantle. Same log warning.

Fixed in 3.5.0.18 for 1.18.2. No plans to backport to 1.18.1
