Haha! Don't worry, keep sending! ^^
As I can see in your video, you should also set the region on the tiles the event is.
Also, how do you set up the events? Can you show to me a screenshot of them?
After they fall, if you don't restore them, you need to move them to another coordinate. See the screenshots of an example of a falling platform that is restored.
If you don't want to restore the platform, you can change the event location on Page 3, or just erase the event.
