Tutorial or Brewing bug?
I may have only brewed a potion or 2. I know how to play, so I don't know if the game showed me this before or not. But the entire game froze when I opened the Brewing screen, and saw this.
Not even the back - button is working. So I closed the game, and tried to open Brewing again. It stopped with the same message, and froze again.
I opened Brewing again, the next day. I saw no such message, but it wasn't let me select a cauldron.
@stevenrice this is their top priority. I already reported the bug.
