Hey guys, I know how to unstack (split) items in my inventory. But how do I stack them up again? Shift+drag onto each other doesn't work, so that's not it.
Crafting characters can also stack items. At least in my game I do get a choice. In the cases where you try to stack items that would otherwise combine via crafting (e.g. small healing potions) you see two tabs (craft and stack). Per default the character would craft.
