Ahh, I see what you're talking about. True, when you play the game the platform is layered in front of the furniture. I found that when you use camera mode to take a capture, it reverses the order of importance, and the platform is behind. So while the stairs are in the background on that image, it's a result of camera mode, and in game Eiv sees the stairs in front.
Thank you so much. You've put my troubles to rest. I can sleep easy now.
