Both copper and bronze cannot be crafting into ingots - if you put a block in a crafting table there is no output.

SurvivalPlus-1.16.1-0.1.3

Thanks for finding this. It's actually a bug in 1.14-1.16 due to my new compatibility for Silent's Mechanisms. This bug also affects the bronze/copper nuggets as well as the block to nugget recipes too. This has been fixed and will be released with the 0.1.4 update sometime in the future.

Don't ask me how cause I have no clue, but I did fix this, tested the fix and uploaded the fix for this issue. But when playing with 0.1.4b it's still broken and I can't find any trace of my fix so I'll release a new b version for 1.14/1.15 and a c version for 1.16 that'll fix this again.
