when you boot a world, FFB throws an error stating that it has a registry error

"Expected item to be an item. was unknown string 'malum_runewood_sapling'"
can not find anything to fix this on FFB's end.

mod link: https://www.curseforge.com/minecraft/mc-mods/malum

cant find the registry that FFB seems to autogenerate and it doesnt like me trying to use the override to disable the malum sapling

Farming for Blockheads doesn't seem to have any inbuilt Malum compatibility, probably some other mod, a datapack or MarketRegistry.json is adding it

I came to talk about that, but found the issue:
it's a typo in the malum jar, under data/malum/farmingforblockheads_compat/sapling.json, should be malum:runewood_sapling
