Hitting any passive mob from DivineRPG with a melee attack instantly crashes the client when it happens on a server. Singlepalyer is fine. We play in version 1.16.5 / Forge 36.2.34

I asked the Divine RPG deves what they thought about it and they said it might have something to do with how the mod checks for aggro.
