Lephantis glitch

[(PSN)Boomstickman98]

So, I was playing with a friend of mine about two weeks ago. I ended up agreeing to help him defeat Lephantis after he had reported that he was not encountering the usual bug of the corpus mouth not opening. We get through to the end of the fight just fine, but when I landed the killing blow on the boss's second phase, it just froze in place for me. For my friend however, Lephantis was still moving around and attacking him apparently. He managed to finish it off and we got out of there just fine, but I figured it might be best to bring this up so DE can fix this.
