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. isnt the sapling just a normal sapling?

The issue was quite literally me being incompetent and tired and using a "_" instead of a ":". Fixed in InDev

Any estimate on when this will be published? Unfortunately, makes a modpacks look very unpolished because you are bombarded with a bright red error message in game chat on every world load....

you can fix it manually by editing the json file in the jar(its what I did), or maybe with a datapack, not sure about that one though
EDIT: Will only work on private modPack, not on published one
