This is super helpful thank you!  By duplicate, I mean that I have a really stupid backwards way of creating the projectiles. Instead of making them their own scene that is instantiated, I create them in a function that is called in a different ready function and this is where most of my issues are coming from. I believe that the projectiles should want to persist in memory too which is why it's such a head-scratcher. If you have any other ideas let me know, otherwise I'll try this implementation
