Elven city. Move Dwarven miners near a rock pile, and task them to mine stone. They do so, for a while, then wander off as though they "lost" where the rocks are and are searching for them. Note - this occurs irrespective of whether they were specifically tasked to a stone pile, or tasked to mine stone near a stone pile.
Also note that they don't actually seem to be able to mine the stone (no resource generation occurs)
