Describe your issue

If my friend shoots one of the graveyard ghosts, the entire server stops functioning and then crashes when I attempt to close it. It reopens fine, but it reverses the last couple minutes when we log back on.

I see people reporting this in the discord server, but haven't seen a report here and also haven't seen a mod respond to the reports yet.

Steps to reproduce the issue

If he shoots a ghost with this bow, server will stop responding, it crashed my game and froze the friends with the bow's game.

This bug happens when an arrow with Piercing capabilities hits an entity that is immune to arrows. Trueshot gives a bow piercing attacks while ghosts are one of the mobs immune to all arrows. As far as i'm aware there is no way for us modpack devs to fix this on our end, so for now just try not to shoot an arrow-immune mob or remove the trueshot/piercing enchantment.

Other things that can cause this is the vanilla crossbow with the Piercing enchantment and the shielding effect from dungeons gear which also provides full arrow immunity so it seems to be an error with forge not just a single mod interaction
