The Gatherer profession can cause some non-forage items to be doubled. When this happens, the player gains 7 XP for the duplicate item (even though the original item granted no experience). The items affected by this bug are items sitting on the ground in [[the Mines]], namely [[Quartz]], [[Earth Crystal]]s, [[Fire Quartz]], [[Frozen Tear]]s, and [[Dinosaur Egg]]s. (Other items found on the ground in the Mines, namely [[Red Mushroom]]s, [[Purple Mushroom]]s, and [[Fiddlehead Fern]]s are considered forage items, so they always grant foraging experience and any Gatherer duplication is not a bug).
