Quark Backpack Plus server crashes on startup – what to do?

Quark Backpack Plus officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Quark Backpack Plus – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Quark Backpack Plus consumes the most tick time.
