RamPackWobble The for each blue sprite on line 2 runs exactly ten times, once for each iteration of the outer loop. The picked instances list after a "Create object" get limited to that particular instance, so the blue sprite already on the layout never get picked for line 2.
t4u What I meant is if you create multiple objects in a single event and you want to iterate through them afterwards, you're better off duplicating the creation event and doing the iteration on this one. It's hard to explain, so here's a picture. The "creation event" is a simple "start of layout" in this case.
