There are two answers to this situation. The first type: since you can get a wild bee suit to do the task, someone has become interested in it and used it to shoot indiscriminately, turning elves and self into rare elves (this may be even bigger, because you said that the self-elf does not exist). The second one: you see a rare elf, but you are too slow. By then, the elf has escaped, but the system will say, "This elf seems to be gone." For this kind of thing, you have to give it a try and think about whether this rare elf exists on this planet. Go and have a look if you have it. If not, just ignore it!
