Crash when clicking in Furnace container – NullPointerException in Thirst mod (v1.20.1-1.4.0)

[2022110019-source]

When interacting with a furnace container, the game crashes due to a NullPointerException in the Thirst mod’s mixin for AbstractCookingRecipe. It seems the mod attempts to access NBT data from an ItemStack that is null.

Crash Report (excerpt)
