SlashLoot

0.5.3 — 2026-11-01

Containers that behave, and loot that stays put. Thanks to TheArchictect on CurseForge for the report that started this.

• Sound and animation now play on every open. Loot chests and barrels only opened properly the first time. After that they stayed silent and still until the block reloaded.
• Lids stay open while the menu is open. They used to shut after a quarter of a second, with the close sound playing over the open one. Barrels had the same problem.
• Trapped chests hold their redstone signal for as long as somebody has them open, and it counts every player using the chest.
• Items stay in their slots across restarts. On Minecraft 1.21.4 and older, a player's loot used to pack itself into the first slots each time the server restarted. Loot saved by an earlier version packs up one last time when you update, because those saves never recorded the original slots. Nothing is lost, and from then on it stays put.
• Upgrading a world past 1.21.4 keeps everyone's loot. The newer save format could not read the older one, so all personal copies were silently discarded and re-rolled.
• Chest boats work like chest boats. Clicking boards the boat again, and sneak-clicking or the inventory key while riding opens your loot. Those two used to show an empty chest.
• Vehicle menus have proper titles, such as "Oak Boat with Chest", as in vanilla.
• NeoForge listings are now accurate. The 1.21.1 jar never ran on 1.21, and the 1.21.3 jar never ran on 1.21.2: NeoForge refused to load them. Those versions are no longer listed.
• NeoForge 26.3 is now a full release. It was marked beta only because NeoForge was.

Before you update

• Going back to an earlier SlashLoot after running this one is not supported.
• Moving a world from Minecraft 1.20.1 to 1.20.5 or newer keeps every item in its slot, but stacks in personal copies drop to 1. Enchantments on those items may be lost too, though that was not measured.

What was tested

• Every file on a real server: all 25 files started on every Minecraft version they are listed for, 34 combinations from 1.20.1 to 26.3, including the Forge file on NeoForge 1.20.1.
• Every file with a real, unmodified game client: 26 runs covering all 25 files, plus the Forge file on NeoForge 1.20.1. Each run covered three open-and-close cycles on trapped chests, double trapped chests and barrels, then single chests, double chests, shulker boxes, chest minecarts, hopper minecarts, chest boats (boarding, sneak-click and the inventory key), and slots across a server restart.
• Singleplayer: all 13 Fabric files in a real game client's built-in server.
• The shipped Forge file on installer-built Forge and NeoForge 1.20.1 servers.
• The bug itself: the same run against the published 0.5.2 reproduced the silent chests and the broken boats.
• Two players on one chest boat (Fabric 1.21.1): each gets their own copy.
• Upgrading a world with loot in it: 0.5.2 to 0.5.3 on Fabric 1.20.1, 1.21.1 and 1.21.5, Forge 1.20.1 and NeoForge 1.21.1, plus 0.3.0 to 0.5.3 on Fabric 1.21.1 (the old file names), Minecraft 1.21.4 to 1.21.5, and Minecraft 1.20.1 to 1.20.5. Each kept the loot through a second restart.

Not tested

• Alongside other server-side mods.
• Loot in naturally generated structures. Test containers carried the same loot data worldgen writes, but no structure was explored.
• Loader builds other than the ones tested, and game versions released after this one.
