Flying Crocodile (bug)

Over at floor 4,there are these water crocodiles that glitch out and bug away.Same goes to leafrays because after a while the crocodiles will start spinning and flying/teleporting.The leafrays over at floor 3 are bugged too because they will fly away and disappear in an instant.After a while of killing them,they start going invisible and hitting you from nowhere.Not only that,they can glitch u into the ground.Please fix this
