not sure but it might be somthing with the Scale thing, might be messing up the limits, since the top might be to so far, that it does not render, making it able to get out of the screen?
Heh, sorry about that. It's something that I have to fix eventually. Not a critical bug, but not super simple to fix either. I'd need to rewrite some code in order to be able to teleport characters without breaking them. A quick restart should be all that's needed for now.
