When you consume the last food item of a stack, it shouldn’t switch to a different food item if I have additional stacks.
When you consume the last food item of a kind, it should switch to the next most potent. I was in a Echo Knight fight and consumed my last food item of a kind and then it switched to mushroom soup… while I had tonnes of other tier 3 food items.
This happened after patch 1. So whatever was changed this is still quite annoying.
