Potion brewing issues, says i dont have enough gold when i do.

[Bobbybrown]

For some reason this has happened twice, with appraise I am very efficient at brewing potions, however for some reason today twice, at my normal price it said I did not have enough gold when I do. I prepared 2 casts this time and tried the full batch and it failed, I took off the last potion for the next one and it succeeded, however I was brewing 5 potions for 75 coins each, when I brewed the 4 potions it brewed for 202 coins, averaging at 50.5 groats each, I do not know why I couldn't brew all 5.
