Never forget what the in-game tutorial showed you earlier!
For the Rising Station to successfully make bread from the grains you put into it (Wheat or Rye), you *must* fill it with water from the Well -- which is
located directly below the Oven/Recycle Bin in Medieval Dines.
- grab water from the Well
- tap the Rising Station to fill it
- observe the number go from a RED '0' to whatever new number in BLUE, depending on how much you have this appliance upgraded.
TIP:: the number on the Rising Station means how many loaves of bread can be made before it is exhausted of water. At that point, it needs to be replenished with more water from the Well. Now get back in there and bake that bread!
