There is something strange about spawning sprites.
Player_Ship is spawning 4 object in total - 2 different and 2 same with different instance name variable.
Every object is spawn on a specific image point.
When you run project it look like one of the Player_Ship_Engine_Side object (the one one left wing) is flickering and there is one more extra object on Back_Engine, flickering as well.
Same thing happens when you switch object spawn to system create or when you change image points from names to numbers
I found the way to fix that by simply moving event 2 below event 3 so it spawns Engine_Back first and after that Laser_Light and Engine_Sides.
I'm using r103 on win 64, here's the file: spawn issue.capx
