trouble with spawning actors

disparition

If anyone can help be i appreciate, so i have this problem. i have 4 actors lets say actor 1,2,3 and 4 and what i want to do is that when i double tap actor 1 actor 2 appears and so on until you get to actor 4 and then spawn actor 1 again to get the cycle start all over (i do it with 2 taps because i also want to be able to drag and move the actors by holding them down) but the problem is that when actor 1 spawns from actor 4 the game freezes and when you double tap actor 1 it doesnt spawn actor 2, the way that i have my codes are:
i create 4 different game attributes integers (tap1, tap2, tap3, tap4)

Are all the actors the same size (Q: could you simply change the image rather than the actor ?)
