When you shoot a mob with an arrow, the arrow fired appears okay, but when it hits the mob it turns completely vertical with the top facing down.

Sorry for a late reply. I'm not sure whether this bug is still a concern with the current version, as I have forgotten about submitting this. I'll double check everything.
Edit: I just double checked, and it appears that this still happens.
