The Lot manager now shows you why lots are not in the list of available lots to chose from. There are 4 possible reasons:
- You just cannot afford it
- Draftland lots are only available if you own the corresponding kingdom lots
- Kingdom street lots are only available if you own at least 1 main lot
- You cannot buy a lot that you have dibs on.
The system simply shows how many lots were hidden for each of those 4 reasons (if applicable). I hope this clarifies the form contents a bit better.
