CobbleStacker
CobbleStacker is a server-side Fabric mod that reduces lag by automatically merging nearby identical mobs, ground items, and spawners into a single entity with a stack counter, fully compatible with Cobblemon.
CobbleStacker 1.1.0
release17 марта 2026 г.CobbleStacker v1.1.0 - Changelog
Spawner-Only Mob Stacking
Mobs will now only stack if they were spawned by a mob spawner. Natural mobs (ones that spawn in caves, at night, etc.) will behave completely vanilla and
won't be stacked together. This makes gameplay feel much more natural while still keeping your spawner farms optimized and lag-free.
This is enabled by default. If you want the old behavior (stack all mobs), set "mobOnlySpawnerStack": false in the config.
Item Nametag Visibility Fix
Fixed a bug where setting "itemNametagAlwaysVisible": false would make item stack nametags completely invisible instead of showing them when you're nearby
(like mob nametags do). Now when set to false, item nametags will appear when you're within range of the item stack and disappear when you walk away

CobbleStacker 1.0.3
release11 марта 2026 г.The crash was caused by a rare timing issue — when the server was processing item stacks, another mod or the game itself could add or remove entities at
the same time. This corrupted the internal list Minecraft uses to track entities, causing the server to crash.
We fixed it by making the plugin work on a safe copy of the entity list instead of the live one, so it can't be affected by changes happening at the same time. You shouldn't see this crash anymore.

CobbleStacker 1.0.1
release10 марта 2026 г.● Changelog v1.0.1 / v1.0.2:
Fixed console spam caused by vanilla Minecraft logging death messages for named entities. Since stacked mobs have custom display names (e.g. "x2 Glow Squid"),
the server would log "Named entity ... died: ..." every time a stacked mob died. The fix clears the stacking nametag right before the death logic runs, so
vanilla no longer treats them as named entities. Player-applied nametags are preserved and unaffected.
