Continuity: On the floor, behind where the skeletons stand is some assorted treasures, like vases, boxes, pots, scrolls, coins etc. The treasure on the floor [near the gold circle on the floor, which is clearly visible when Juni snatches the medallion and legs it] changes [eg. thing appear, disappear and change position] from when Juni ponders about taking the medallion, to when he takes it and runs.
