Trying to fire a bedrock crossbow that is loaded with a rocket will crash instead of firing it.
To reproduce this behavior, you just load a rocket into a bedrock crossbow and attempt to fire it. The bedrock crossbow we used was enchanted with sniping, piercing, and quick draw.
The expected behavior is that it would fire the firework rocket.
The version of the mod we are using is spectrum-1.2.8-1.18.1-midgame9. It's on a 1.18.1 fabric server.

New information made available via testing:

A bedrock crossbow won't crash if it lacks the sniping enchantment, but it will crash with normal arrows (along with rockets).
Normal (vanilla) crossbows also crash with the sniping enchantment applied.
