Shard's Compats: Voltaic-Sable Compat

A server-side compatibility mod that lets Voltaic survive on Sable physics airships, with optional Ballistix support for ordnance on Create: Aeronautics contraptions.

This mod patches bugs that appear when grid-based power and ordnance mods are assembled into Sable sub-levels. It is server-side only — players connecting to a server do not need it installed.

What it fixes

With Voltaic + Sable (required)

Block duplication on disassembly. Disassembling a physics object could duplicate blocks on the structure's edge — the block survived in the world and dropped as an item. This is patched.
Overworld-to-sublevel changeover. Fixes the transition so grid power and connected machinery survive being assembled into, and disassembled out of, a Sable sub-level.

With Ballistix (optional)

Dispenser stack bug. Deploying from a dispenser failed to subtract the deployed item from the dispenser's stack. This is patched.
Launchers and turrets on contraptions. Allows Ballistix launchers and turrets to function while mounted on an assembled Create: Aeronautics contraption.

Requirements

Mod Required? Notes Minecraft 1.21.1 Yes NeoForge 21.1.230+ Yes Sable Yes The physics / sub-level engine Voltaic Yes Ballistix Optional Enables the launcher, turret, and dispenser patches

If Ballistix is not installed, the Ballistix-related patches are skipped automatically — the Voltaic + Sable fixes still apply.

Installation

Install on the server alongside Sable, Voltaic, and (optionally) Ballistix. No client-side installation is required.

Notes

This is a compatibility patch, not a content mod — it adds no blocks, items, or recipes.
Built for the Aeronautic Warfare modpack stack: Create, Create: Aeronautics, Simulated, and Sable.
