"If you have to plant a third type of bean when there are already two other types on your fields, you may put the third type of bean in either one of your fields. This will cover up the beans that were planted in the field before, for the time being. That first type can only be planted again or harvested after the new type has been harvested. This means that there may be several different types of bean in the same field."
Example: field 1 has 2 mean beans, field 2 has 2 sour beans. Player then places 2 broad beans in field 1.
1. Subsequently, can the player place a stink bean in field 1 or field 2? 2. Can the player place more mean beans in field 2?
