I presume there's a missing call in the entity arrow that sets them to pick-up type "Creative Only" or some-such.

Are you saying that you should be able to pick them up, or shouldn't?

Sorry, shouldn't be able to pick them up.

You currently are able to.

I mean, I don't see an issue with that

Ah, it was Darkphan who noticed it and thought that you shouldn't be able to pick them up. I was filing the bug on his behalf.

All good. Honestly I can see both sides of this, but I think getting a bunch of free arrows is far from an issue, so I think I'll leave it like it is.

Okay, no worries! That's totally fine as well. It is a reward after all.
