When crops change, the Orchard map needs to be updated. Some examples of changes include:
new block structure
new production status
Blocks can only be edited from within an individual property, learn how to navigate to a property here.
Edit a crop/block
Select the Crops/Blocks workflow from the sidebar
Select the block to edit
Select the ellipsis (three dots at top right of side bar when in an individual block)
Make changes as required
Click Save to adopt the changes or Cancel to go back
If you cannot see the edit button, you do not have permissions to edit and should talk to your administrator.
