ok in that case i trust you, i was just afraid it was a "i heard a guy, told a guy who told my friend, who told me" kinda story ;) I can confirm, I had 6k gold ore in my bank and I got both rocks within 200 or so smelts. A technique that might help though, I only had 26 ores in my pack at a time when I smelted so that the rocks always had an inventory space.
