Instead of killing the actor, on your "when collided" or whatever you are using to detect its death, have it run the animation, then switch to an animation that is transparent and has no collisions, wait x seconds, then switch back to the first animation. You may also want it to set a boolean so that you cannot control the actor during that time (in your control blocks have it check whether that boolean is true or false)
Also, did you get my PM?
