The following message appears when this happens (even if an extra flask is filled):You mix such a potent potion that you fill an extra vial, thanks to this incredible mixing station! It has been sent to your bank. It can be placed anywhere that you can light a fire and is both visible to and usable by all other players. It vanishes after being placed for 5 minutes. If the well vanishes but the player has not finished making all potions, they will continue making but the well's effect will not work.
