Timeline Event starting automatically

I set up a sun day/night animation that is triggered by pressing P, and stopped by pressing backspace. It works fine when I play it in the editor. But when I package the project and run that program, it starts playing automatically. Why is it acting different when I package it? Is there a better way to have it not play until I press a button? Attached is my level blueprint which shows how I have it all hooked up.

Thats odd.

You can try adding a print right after the P input being pressed. Thus, you could check if this is REALLY being called from there, otherwise the timeline is being called by some other way.
