Just trying alchemy for the first time and I'm noticing that potions I make don't seem to want to stack with potions of the same name that I find. If I save/quit and then come back into the game they will then stack with the sort button, but if I ever separate them again via the crafting containers, they won't stack again.
Patch notes for the unreleased 1.04 patch: - FIXED: potion stacking stops working after you save, reload, and put it in a craft tool.
