According to the wiki:
Goes to next layout. If current layout is last, goes to first layout. If current layout is the only layout, reloads layout.
I tried this in the tutorial I've been following and it closes the application when there is only one layout instead of reloading it.
I created a new project added one sprite added the bullet and warp behavior to the sprite. Then added one event, "on spacebar pressed go to next layout." It also closes the application instead of restarting it.
BTW, is there a workaround?
