One Hit KO server crashes on startup – what to do?

One Hit KO officially supports fabric for Minecraft 26.1.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with One Hit KO – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if One Hit KO consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
