Okay, so i'm finished with my board, and i'm ready to overwrite. But there is a error that says that there's a dead end on my board but i can't see one. What's wrong?
It means that somehow, beginning from the start space, the player could reach a path that abruptly ends. The game will usually crash when this happens so the editor tries to prevent you from creating dead ends.
I can't say why a particular board encounters this error unless you provide at least a screenshot.
