At the beginning of the game, nothing will be a harbinger of trouble until you find several varieties of resources and equipment, which will fill up several available inventory cells in an instant. All picked up items (if they are unequipped) do not affect the character's loadout, but are stored in separate cells. And their number, unfortunately, is limited. In the case of resources, bombs, food - items will be stacked, but for each type the stack has its own limited size. For example, you can store up to 20 units of wormwood in one cell. If you want to pick up the 21st, the next cell will be occupied.
To unlock new inventory cells, get to Sacramenta and find a merchant who will allow you to do so for a special resource.
