These statements in script

mods.atum.Quern.removeRecipeByOutput(<item:atum:emmer_flour>);
mods.atum.Quern.addRecipe(<item:atum:fertile_soil>, <item:atum:fertile_soil_pile>, 3);

fails. Both producing "No compatible methods found".

You should not have "item:" in the script. just "atum:emmer_flour"

@sscards55 unfortunately, no. Now the error tells me: "Invalid bracket exception: no prefix atum". And that shouldn't be case anyway, because all of my other scripts works fine with prefix (and they should).

Never mind ignore what I said.

I´ve not updated the documentation on the wiki.
Should be like:

<recipetype:atum:quern>.removeRecipeByOutput(<item:atum:emmer_flour>);
<recipetype:atum:quern>.addRecipe(<item:atum:fertile_soil>, <item:atum:fertile_soil_pile>, 3);
