Frequently Asked Questions

Bacillus server crashes on startup – what to do?

Is Bacillus compatible with fabric and neoforge?

Bacillus officially supports fabric, neoforge for Minecraft 1.21.3, 1.21.2, 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Bacillus – how to optimize performance?

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