If you got your game in the last few hours and it still happens, I need to know so I can try something else.
If you DO get stuck in a weird location, you can save your game and come get a fix, there is a cheat code that will teleport you back to a normal position. But like I said, if you got your game in the past few hours and this happens, LET ME KNOW before you fix it, because I need to make this stop happening.
Hit F10 to bring up the cheat code box
girl_walker_worldmap.x = 1000; girl_walker_worldmap.y = 500;
and then click on OK.
