I've only seen two stages so far. The main one, with the dolls, can't be stood on (or at least I could run through it) but the second one is specifically designed for screenshots. This is the one that has a NPC who asks you to be considerate and not stay on it too long. The first thing that happened was numbskulls standing on it, or directly in front, and going afk. Similarly the NPC handling the maps was surrounded by afk players this morning on Leviathan which made it very difficult to select her to interact.
