My vault was almost full, and when a worker tried to teleport gold into it, there wasn't enough space, so part of his gold transported, and part of it remained above the chasm. Later I picked up the pile manually and dropped into my vault, but its image remained there forever. It even remains there after loading save.
You will need this map to load the save.
