Sprite getting randomly destroyed?

Hi everyone, Theres a problem with one of the sprites in my c2 project.

the problem is that after about 3 seconds the sprite gets destroyed and i dont know why.
i have not made it get destroyed after 3 seconds.

Please help.

Post your .capx or images of your events, tough to do anything otherwise. :)

It could be hidden under something, suddenly moved off screen, or destroyed with another instance.
Too many possibilities, but in my experience it has a good chance of having something to do with "picking" in events. (it gets picked by mistake, or doesn't get picked when it's supposed to.)
