Frequently Asked Questions

Ores4Gen server crashes on startup – what to do?

Most common cause: wrong fabric 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 (1.21.8). You can switch loaders with one click in the panel.

Is Ores4Gen compatible with fabric?

Ores4Gen officially supports fabric for Minecraft 1.21.8. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Ores4Gen – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Ores4Gen consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
