The chess piece that's located below the rim of the area just before the final boss shows up on my radar, but it's not on the rocky ledge that YouTube videos indicate. My radar indicates it's in the column between the two rocky ledges, but it's not visible and now matter how I approach the radar-indicated spot I cannot collect it. I've spawned in multiple times over yesterday and today and that's not resolved the problem. It's the final piece I need for the 60 pieces, so it's frustrating. Anybody else experiencing this? Any work arounds?
