Goety Owned Null Guard Fix

A tiny (~3KB) Forge 1.20.1 patch that fixes a recurring crash from Goety summons.

The Problem

When Goety summons such as Inferno or ZombieServant take damage, the game can crash with a "Ticking entity" NullPointerException. It happens most often in the Nether, with multiple same-type summons nearby, or with ownerless summons. The crash stack always points at Owned.java:186 -> Entity.java:2236.

Root Cause

Goety's Owned.isAlliedTo(Entity) forwards a null entity to vanilla Entity.isAlliedTo. The hurt-revenge target AI passes a cleared lastHurtByMob() value while propagating damage to nearby same-type mobs, and vanilla 1.20.1 dereferences the argument without a null check (p.getTeam()) -> NPE.

The Fix

A mixin injects a null guard at the entry of Owned.isAlliedTo: it returns false for a null argument (a null entity can never be an ally). No gameplay balance and no AI behaviour changes - it is a pure null-safety fix.

Compatibility

• Requires Forge 1.20.1 (47.x) and Goety 2.5.56+.
• Works alongside RevelationFix, Goety: Revelation and all Goety addons.
• Install on both the client and the server. For an integrated server, the host must have the mod installed.
• Contains only a mixin; no Goety code is included. MIT licensed. Remove the jar to uninstall.
