Not sure but I would def message Tyler Lansdown, Boon or 16 Bit on twitter about it. They look at what people say and address it so you could see a patch. They cant do anything if you dont say anything about it

I found a sorta workaround. Try pressing interact+down your character should do a jump and the consumable should activate. But it only seems to work on the first consumable you choose.

I found a work around for Xbox using companion mode. Companion mode lets you use 2 controllers for a single player. The problem is most of the good fight sticks don't get recognized as an authentic Xbox controller so you can't enable companion mode. I used a one of those "connect any controller on your xbox devices" called the Cronos Max Plus. This was able to get my Razer Atrox to show up as a real xbox controller allowing me to use companion mode. The Cronos lets you connect a real controller for a second to authenticate the Cronos as a valid controller. Now I remove the real controller and plug the Atrox in. The rest is self explanatory. Now I can use a second controller for Krypts or consumables all connected to player 1.
