About this Mod

⚠️ Developer Version of CoreClient ⚠️

This mod version includes diagnostic commands such as /client settings killlwjgl, which will crash the game and display a native JNA window. Before the crash, a confirmation GUI appears with two buttons: Confirm Crash — proceeds with the crash, and Cancel — aborts it.

Use these commands strictly for debugging purposes. This feature is not recommended for regular gameplay and is intended only for developers or advanced users.

Frequently Asked Questions

CoreClient server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is CoreClient compatible with forge?

CoreClient officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with CoreClient – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CoreClient consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
