Damn never had this and dont even know why would it happen
Happens in my Godot games sometimes, maybe something to do with inputs being processed during the micro stutter that happens when the game first loads? I added a 0.1 seconds time window on load where inputs are discarded to prevent that from happening, it shouldn't cause any issues when loading since it's such a short time but it might stop players from accidentally starting the game while looking at the ground or the sky.
