I'm in 1.7.10, using "InventoryTweaks-1.59-dev-152"

When I eat a mushroom stew, it changes into an empty bowl instead of being replaced with another in inventory. It happens without any other mods (except forge). With biomes o plenty, their variation "Shroom Salad" works as you would expect (it's replaced with a new one).

I think I see why, although I'm surprised a different version works if it does the same thing as mushroom stew with leaving a bowl behind in the slot.
