Hyzen Kernel

HyzenKernel (Hytale Early Access)

HyzenKernel is a set of essential fixes for Hytale Early Access servers. It was originally created to stabilize our server Hyzen.net, and we decided to share it with the community. It is an improved fork of HyFixes.

Two plugins, one goal

Runtime plugin (hyzenkernel-X.X.X.jar): runtime fixes using sanitizers and hooks.

Early plugin (hyzenkernel-early-X.X.X.jar): deep fixes via ASM bytecode transforms at class load.

Key improvements (summary)

Prevents world thread crashes from spawns, world map issues, and invalid refs.

Prevents kicks from instance race conditions and interaction timeouts.

Fixes null/invalid component errors that break interactions.

Reduces shutdown errors and task submissions to dead worlds.

Quick install

1) Runtime (required): place hyzenkernel-X.X.X.jar in mods/

2) Early (recommended): place hyzenkernel-early-X.X.X.jar in earlyplugins/ and enable early plugins

Configuration

Generated at mods/hyzenkernel/config.json with toggles for fixes and logging.

Notes

Recommended for servers with instances, portals, and custom content.

Compatible with vanilla Hytale Early Access servers.
