We originally had Cannonballs, Coconuts, and Sub-Wafers going into the Consumables slot, but only having access to one at a time broke those Pirate hero builds, so we left them in the weapon slots for the time being to avoid that (since we were out of time to deliver a more robust solution alongside Wildlife).
We are still planning to move them into the Consumable slot, but we absolutely don't want to break those builds, so we're also thinking about how to give you more flexibility - both in how many Consumables you can carry and where you can slot them. This work is still in development, so I can't commit to a timeline or the exact details of what the solution will look like, but keep an eye out for further updates in the Homebase Status Reports.
