Ah, that would make sense, because when you call a script with external, it's sort of treated as part of the script that called it. Since the script that called it is attached to a dying creature, it's not too surprising that the whole thing collapses when it the sprite is killed (ie. when it comes to a wait).

You can get around this by either using script_attached(1000) or using spawn isntead of external. In either case, make sure put kill_this_task at the end.
