Umapyoi Addon Pack server crashes on startup – what to do?

Umapyoi Addon Pack officially supports fabric, forge, neoforge for Minecraft 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Umapyoi Addon Pack – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Umapyoi Addon Pack consumes the most tick time.
