Aeronautics Levitite Server Fix
by dacite
Aeronautics Levitite Server Fix lets Levitite Blend crystallize on dedicated servers, a step that Create Aeronautics otherwise fails at there.
What it does
On a dedicated server, right-clicking a Levitite Blend with a catalyzer, a torch, flint and steel or a fire charge does nothing, and the server log records an error. This mod removes that failure, so the blend crystallizes the same way it does in singleplayer, where the integrated server already works. The change is a small server-side fix applied to Create Aeronautics, and it covers only that interaction.
The jar goes into the server's mods folder, and the environment is server-side only, so players join without installing it. It requires NeoForge and Create, and it names Create Aeronautics as an optional dependency. The mod is published only for NeoForge, for 1.21.1, and the latest file is 1.1.0, released on 2026-06-14. The code is released under the MIT License and is not open source.
The fix is tracked as upstream Simulated-Project issue 664. The root cause is documented in a write-up by the author, and the mod's Mixin targets reference class names only, so it compiles against Create Aeronautics as a dependency. Newer upstream builds of Create Aeronautics already include the correction, so the mod is not needed there.

How it compares
More Levitite is a NeoForge mod for 1.21.1 with the client and server environment, under All rights reserved and not open source. Aeronautics Hot Air Fix is a client-side only NeoForge mod for 1.21.1, licensed under 0BSD and not open source, so it does not touch the server behavior this mod fixes. Create Aeronautics: Portable Engine Liquid Fuel is a NeoForge mod for 1.21.1 under the MIT License, adding a different feature rather than the crystallization fix.

What the author says
A tiny server-side fix for Create: Aeronautics that lets Levitite Blend crystallize on dedicated servers. It works in singleplayer because the integrated server shares the client distribution.
