I really really love this game, but I'm experiencing an issue. When I get to the cake level, after I drop the cake, I can't make potions with the potion machine.
I can't get past the second adventurer, Violet, but I've also had this happen with the adventurer before, Glamdalf, when I'm not quick enough to make it. I can interact with everything else just fine, but no matter how many times I re-interact with the cake and no matter what I try to give the customer, the potion machine simply ceases to be interactable.
