I'm dabbling with building fields outfoors. I put the field next to a pool, fully knowing that the field itself wasn't muddied. Nevertheless there was soil there, and the field was successfully built and later planted with wild strawberries.
Encouraged by this and finding some suitable seeds in my stores, I tried to create another plant, just like the succesful one above, next to water, with soil but without mud. The grower never planted it. The building just says that it's waiting Farming (Fields). It stood there forever, and nothing happened. I even took all the other duties away from the grower, leaving only Farming (Fields), and the guy just went slacking, obiviously without any intention of building the plant.
Convinced that he'd never do it, I removed the building that was never built, and tried another plot, with the same result. Why is this happening? Why did the grower create the first field without much delay and without any problems, and then never bothered to make the other designated fields on similar locations?
The path is not blocked, it is right next to embark location, a nice big open space.
I haven't done anything with burrows, active or otherwise, that's too advanced for me yet. Judging from what little I know and guess about them, the very farmer was happily gathering lots plants around the said field, until I told him to stop so I don't think this is about that either.
