Describe the bug
when shooting any kind of arrow at trolls, it bounces off(not the bug), and can be picked back up, but when a bow has the back to the chamber enchant, the arrow bounces off, and is returned to the chamber at the same time createing 2 of 1 arrow. this can be a normal arrow, or a hydra arrow, any kind of arrow works.

To Reproduce
get a bow with the back to the chamber enchantment, shoot arrows at trolls and record how much you have at the begging
Expected behavior

idk how you guys intend for it to happen, but you should either get 1 arrow back and not have it drop to the ground, or have it drop to the ground and not return to players inventory

Additional context

The Back to the Chamber enchantment is now disabled, so this issue can be closed.

Can't think of a way to fix this. This isn't really an infinite dupe either (and its also a risky one). Gonna leave this as intended.

This can be fixed hopefully with Asterixxx's Ice and Fire fork. Or another mod that emulates Back to the Chamber enchantment but only activates the effect if the arrow is consumed. It is neither finite nor risky tbh and is certainly not working as intended.

But the mob will die eventually, right? Correct me if I'm wrong but I thought an arrow bouncing off a mob is a chance to happen. It is risky because you have to go pick up the arrows.

you may be right but I'm pretty sure all of them bounce off the troll, not just an X% chance

Trolls are immune to arrows, so no, they will not eventually die. I suspect this glitch might happen for any mob immune to arrows as well.

This issue is easily exploitable in two ways:

1. Shoot a troll that was exposed to sunlight, it's invulnerable
2. Shoot a teammate, same effect is achieved
