This is a very, very tiny mixin that works with the Open Parties and Claims mod to also protect players from entity attack while in their claim.
It alters the functionality of xaero.pac.common.server.claims.protection.ChunkProtection.isProtectable(Entity) to, instead of excluding Players, explicitly includes Players.
Only required for single player, LAN host, and dedicated server environments. Just drop it into the mods folder; there is no configuration.
If you have a problem, remove this mod. If you think there is a problem with OPAC, still remove this mod instead. The OPAC author should not be held responsible for any issues caused by this mod.
I don't plan to put this onto CurseForge. If you grab this and install it, I will assume you know what you are doing.
