The ratio of the tiles of the main building to the average cultivated area is very poor.
Herbalist:
- At average temperatures he usually only effectively cultivated about 3x4 (compost is used)
- He is a 5x4 building.
- To cultivate an additional 3x4 fields of herbs, you have to build another 5x4 main building.
Mycologist:
- At average temperatures he cultivated almost a entire 4x4 area ( Normal Mushrooms and compost is used)
- He is a 4x4 building.
- To cultivate an additional 4x4 fields of mushrooms, you have to build another 4x4 main building.
This problem could be solved with the same upgrade that the farms have:
- More workers in the main building would be able to cultivate more land from the same main building.
- More yield per field thanks to compost reduces the number of additional buildings/fields that need to be constructed.
