Summary: A conservative, reversible performance autopilot — culls excess dropped items, XP orbs and projectiles under sustained lag pressure. Off and dry-run by default.
Description
Autopilot watches the same sustained-MSPT-pressure and entity-dense-chunk signals Vyvern Stats reports, and takes conservative, reversible counter-measures when a chunk is genuinely over capacity — culling excess dropped items, XP orbs and projectiles.
Safety first:
- Master switch defaults off. Dry-run mode defaults on.
- Every action — real or dry-run — is published to the Vyvern panel. Nothing happens silently.
- Only steps in under sustained pressure in over-capacity chunks; it doesn't touch a healthy server.
Requires: Vyvern Bridge, NeoForge 1.21.1+, Minecraft 1.21.1 (server-side; inert on a client).
- Edition: Minecraft Java
- File type: .jar
- Minecraft version listed: 1.21.1
- How to install: Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. → Download the .jar. → Put it in the .minecraft/mods folder and launch that loader profile.
