Scene Replays are a heavily requested feature, however, due to the amount of variations that each scene could have there would be a lot of setup/input from the player that would be needed prior to seeing the scene.
The scene can change based on what club you're in, what relationships you're in, and choices that you made earlier in the route. So this complicates things quite a bit when it comes to scene replays.
If we had straightforward scenes that didn't change like that then it would be much much simpler to implement. Hell, the 0.49 update has it's first layered CG Scene since it has 40 variations based on your choices. So if you were to do a scene replay of that scene we'd need to setup 40 combinations for you to pick for that one scene.
