Less Tree is mainly worth checking through join path, client files, and server files, server rules, EAC, permissions, and admin recovery, multiplayer sync, disconnect, and restart behavior, FPS, stutter, render distance, and weather load, and server tick, spawn load, and cleanup timing. Do that in a copied save or test server before changing a main world.
Use Nexus Mods listing to confirm exact file names, branches, screenshots, and update notes; then judge the MOD by the in-game parts above, not only by whether the game launches.
- Test with a second client before inviting regular players.
- Write the install rule, EAC state, rollback point, and admin recovery path where players can see them.
- Check the changed feature after reconnect, server restart, and one rollback rehearsal.
- Test the same POI, biome, and blood moon size before and after the MOD.
