Hi, I am trying to make the Shark Potion, I have all the ingredients, but then, it goes horibly wrong! I create the potion, I have a master do everything, then I wait for it to boil, or steam. When I go to the pot, it says no potion is made, or you need 3 more herbs or something like that. I restarted like 4 times already as they died with lack of food. It is really get frusterating.

Unless the potion blows up, it is ready and usable as soon as the villager puts the last herb into the cauldron (white steam will be coming from the cauldron). Assuming that you're using the correct combination and the potion didn't blow up, perhaps you're waiting too long to try to use it? The potions evaporate within a short time (tap the cauldron to see how long the potion will remain), after which you will need to make a new one.

:)Ok I will try that thankyou! I think all my villagers died in the process... So I have to restart. But it`s fun!
