Trident Killers 4 Java

Trident Killers 4 Java 1.2.6 - server crash fix.

Fixes a NullPointerException that could crash the server when a player picked up an item near a piston-powered killer trident. The mod's internal 'turret' attacker was created with the player's own UUID, which corrupted that player's advancement handler and produced a null-connection crash on the next advancement/recipe update. The turret now uses a separate, derived identifier. No gameplay or feature changes.

Only the builds affected by the bug are updated (1.20-1.20.6, 1.21-1.21.1, 1.21.2-1.21.5). 1.21.6+ and 26.x were never affected. Server-side mod - install it on the server.
