I think it was already said somewhere by someone, but I don't really remember if there was any reason for it not being implemented, so I'll try again to ask for animated trigger scenery being played more than once, forward and backward (depending on if it was turned on or off). I don't think there are any levels taking advantage of the way it works currently, while making it work like what I said not only makes much more sense but also gives some really nice possibilities in making levels and tilesets.
