Dissy Block Overlay server crashes on startup – what to do?

Dissy Block Overlay officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Dissy Block Overlay – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Dissy Block Overlay consumes the most tick time.
