BanChest

1.0.1

Fixed

• Offline players are no longer skipped. The reader called three NBT methods that Mojang removed in 1.21.5 (CompoundTag.getList(String, int), ListTag.getCompound(int), ItemStack.parseOptional). On anything newer than 1.21.4 this threw NoSuchMethodError, which the command's catch (Exception) didn't cover — so every offline player reported "had no items to redistribute" and their data was left untouched.
• Armour and off-hand items were being left behind. Since 1.21.9 they live in a separate equipment compound instead of inventory slots 100–103/150; both layouts are now read and cleared.
• Player data is resolved from the main world's folder rather than the first world with a NORMAL environment, which could pick the wrong directory on multi-world setups.

Changed

• Items are deserialised through ItemStack.CODEC, and the NBT accessors that changed shape across versions are resolved at runtime, so a single jar covers 1.21.1 through 26.x.
• Online players' items are collected as storage + armour + off-hand explicitly instead of relying on getContents().
• Failures now report what actually happened instead of looking like an empty inventory: a missing .dat names the path that was checked, and an unrecognised server version says so and leaves player data untouched.
• Offline reads log a breakdown (inventory / ender chest / equipped) to the console.
