I have actually no idea why this warning keeps popping up, even though everthing works as intended.
For context: In my game, you can flip cards arround, obscuring the card type. To do this, i created a sprite 2d called “Backside” that covers everything, and i alternate between it being visible or not through the “flip” and “unflip” animations. This is not the first time warnings like these popped up when i load up my game, but im unsure if i can even do anything about them.
Usually it means the AnimatinoPlayer can’t find the node listed in it’s track. Maybe the AnimationPlayer’s root_node was changed or one of the nodes was renamed without the track updating. I don’t know why these warning only show in the editor briefly.
