It says in the Load menu that there are 6 potions in total on day 8 instead of 8
Also, the max on day 11 is said to be 8 when you're supposed get 3 potions wrong (theoretically, of course, since sometimes you don't have to give potions to the mage Astrid anyway), even though days with the vampire don't count the incorrect potions that result from her conditions in their total (at least that's what I'm assuming from the previous days)
(Don't pay attention to the fact there are 8 correct potions for each day, I just tried to ignore the vampire conditions to get the max amount of money possible)
Also hey I just realized that preset characters have names now in Sandbox! Nice!
