There is NO list to be able to chose any specific Neighbour to work them. They will be worked when the first Neighbour with the requirement for the mayor to complete work on all farms starts working your Regular Facility request. After you claim the reward, the farmer that works them will see a brief notification in yellow text informing them that the Non Workable facilities will also be worked: There can be times where the farmer working them notices that the green grid top left of their game screen is showing more farms to work for you than is usual. The grid will be highlighting in blue, both the farms with regular facility work on them as well as any farms that have non-workable facilities on them. The mayor will then work all of those farms for them. In this example the farm owner has 18 farms with regular facility work to be done but has not claimed the reward yet. In this example the farm owner has claimed the reward and as they have a considerable amount of non-workable facilities on more farms that don't also have regular facility work on them, the farmer working them, is seeing that more than the usual 18 farms can be worked: In the Privileges section: When you claim the reward the background colour in the Privileges section will change to green. When your Non-Workable Facilities have been worked, next time you load the game the background colour will change to pink. There will be days/hours/minutes showing until Non- Workable Facilites can be worked the following week, as long as the season has not ended. In the Rewards section you can also mouseover the claimed reward and see the same information.
