The log between the two woodcutters left to the weaving mill is designated for the labyrinth. Destroying the road between the two woodcutters starts the delivery process and the labyrinth gets finished.
The log next to the quarry is designated for the farm. Destroying the road that connects the quarry with flag where the log is lying around starts, the delivery and the farm gets finished.
I don't know if this observation helps.
