They didn't work for me.
Elaborate your point, sir. I did some hacky things because my events were supposed to do what the tutorial does, and since I can't really make trigger zones, it had to do weird stuff...
Anyway, I don't see how it was breaking for anyone. I made events to set, read, and react to prints. I got permission from Adam487 to use the onPrintChange in there... maybe if I remove that and make it a required add on, it's work out better.
