To Reproduce

Make a world and grab a bow.

Shoot arrows from the bow.

Close the world and reopen it.

Crash.

Alternatively:

Join a server/wander around in a server where arrows are already present. *unsure on this one, just how I found it originally.

Additional context

After the newest update for arrows to gain their override (fine work by the way) it seems its created this new consistent crash.

I tested the mod by itself and JEI.
