AtlasSpigot 26.2 - build 16 (hard tuning tier)

Config update for Minecraft 26.2. The jar is unchanged from build 14 — this ships a second, much harder round of tuning.

Read this before installing

Build 15 crossed the "no visible gameplay change" line. This build goes considerably further. Several settings will be obvious in play:

• nerf-spawner-mobs is on. Mobs from spawners have no AI — they don't walk, path or wander. This is the largest single win here and it will break grinder designs that rely on mobs moving or being pushed.
• Monsters despawn at 28/48 instead of vanilla's 32/128, so distant mob farms will underperform.
• Simulation distance 4 → 3 — fewer chunks tick at all.
• Entity broadcast range 100% → 50% — entities are sent to your client at half the distance, so things pop in later.
• Armor stands no longer tick. Static decorative stands are fine; anything relying on gravity or movement is not.

If you run mob farms or grinders, build 15 is the gentler option and remains available.

Everything else in this pass

Hopper checks 8× less frequent with hopper-amount raised to 3 so throughput roughly holds · XP orbs merge (radius 4.0) · arrows despawn in 15s · container update, grass spread and spawner tick rates reduced · 12 junk item types despawn in 15s instead of 5 minutes · DAB pushed harder (start-distance 12→8, activation-dist-mod 8→7, the value Leaf's own config comment recommends for ticking distant entities less often).

Still not enabled

hopper.disable-move-event remains off. It's the biggest remaining win and the only setting held back purely for plugin compatibility rather than gameplay — it stops firing InventoryMoveItemEvent, which shop, economy and sorting plugins subscribe to. Every plugin still works on this build.

Verified

Boots clean in 10.67s through start.sh. spigot.yml and atlas-global.yml return byte-identical after the server writes them back, and every changed value was confirmed still in place.

Not benchmarked. No measurements have been taken on 26.2, so no performance figures are claimed. Full reasoning for every setting, including what was rejected and why, is in NOTES.md.

Installing

Download both files. Drop the jar in your server folder, copy the config contents alongside it, set eula=true, then run ./start.sh.
