attempting to use the script:
mods.astralsorcery.Altar.removeAltarRecipe("astralsorcery:shaped/internal/altar/constellationpaper");

doesnt throw any errors in the crafttweaker logs but it doesn't remove the recipes

removeAltarRecipe seems to be removing other recipes just fine as I've tested here with sooty marble (and readded under a different recipe name) in the image album above

AS version: astralsorcery-1.12.2-1.10.4
