Blue Sentinel hitting animation glitched.

If you skip to 14:59 you will see Blue Sentinel hitting animation being glitched out, he was deal damage but his animation was glitched. Simple as that, I don't know what made the bug, but clearly it is one. I think it happens when my hitbox model is too close to his hitbox.
