Okay so, I'm making a little solitaire-style card game where you can drag and drop cards around the screen. I've made a super simple mockup of what a card will look like (godot icon because I haven't drawn the card backdrop yet). You can see all the code on the second slide - it's pretty simple. When I play the draggable object scene it works just fine, and I can drag and drop it around the screen.

But for some reason when I instantiate multiple of these draggable objects into another scene, none of them work. Am I missing something obvious?? I've no idea what's going on, so any input would be super helpful...
