Krug spawn point bug

When i played jungle today, i saw the little one krug spawning off the krug-pit. He bounced like 10 meters away, and it staid there. After that, i killed them all, but the one was still outside of the pit, and when i gone to kill him, he ran away back to that point. It had its "spawn" outside of the pit, and i dont know if this has happened to anyone else. I have video about this, but im not sure if i want to upload it with this shitty internet :/
