Can you share a .capx?
When the event sheet is empty it shows the tip: "Events are run from top to bottom". After the bottom of the event sheet the screen is drawn. So if you have them one way round, the object is created, the animation frame is set, then the screen is drawn. The other way round, the object is created, the screen is drawn (before the animation frame is set), then the next tick the animation frame is set. This results in a quick flash of the wrong animation frame for one tick. This is why the order of your events is important.
