I used his update as well on 22.
All buildings on the farms can be sold once the land is bought. With the exception of the cow barn on the bsl farm. I’m not sure why I can’t get that one to be sellable. If you come across a house or shed that can’t be sold let me know and I’ll look into it. The sellpoints etc can’t be sold.
I’d like to add some more crops especially rye, also some stuff like CCM. I just have to find textures and so on for that.
