I remember this option existing before 1.18, as we used it to add a bunch of crops to that list in 1.16 so that I could unify the seeds. But now, in 1.18, it isn't there. Which is odd. I see the code for the line here.

Here is a copy of the configs in the pack: https://github.com/belathus/Wanderlust/blob/main/config/crockpot-common.toml. Even if I delete and regenerate the configs, it leaves out the list of crops.

In the curse forge page we listed the changes:

Unknown Crops now will convert into blocks that have the tag crockpot:unknown_crops, so instead of editing the config file, you can just simply add a tag for the blocks
