All I meant was that you can make an overworld disappear with them. For example, you use "setflag 0x1000" in your script. To make the overworld go away, change their Person ID to 1000. But know that it won't disappear unless the screen resets, which can be accomplished by forcing the OW off the screen, waiting for the player to go off the screen, or by using a "fadescreen 0x0", which makes a little flash and returns to the game.
