Cannot move exit to edge of map

I have an issue where I cannot move the exit to the bottom. As you can see in my screenshot the exit is placed 1 tile above the bottom. Cannot move it all the way down.

Same now on the right side.

And now all of a sudden they start showing up? Something is definitely wrong here :stuck_out_tongue:

Can you post or private-message the exported JSON file? We'll take a look. Thanks!
