So... I want to set on few first maps arrows to make important places or events more visible, some kinda "X marks the spot". But the tiles can't disappear when event is completed! And when I'm doing this via pictures, it's more shitty because pictures are always on top and when the screen is shaking in storm the pictures don't shake. And... I'm posting it here because it seems that it's not possible via events not using "show picture" and "erase picture". Any ideas?
