Peace of Mind Minecraft server setup

Peace of Mind is a quest-based, beginner-friendly Forge modpack for Minecraft 1.12.2, built for Peaceful difficulty by TooGoodMules and chunked_element. Its CurseForge page describes a quest book with over 250 quests that guide players through mostly magic and low-tech mods, aimed at people who are new to modded Minecraft. You install the server from the Modpacks tab, using the pack's own server zip.

Checked against Peace of Mind 2.1.3 on Forge 14.23.5.2859 and Minecraft 1.12.2, October 2026.

What the pack needs

• Minecraft 1.12.2 with Forge 14.23.5.2859. The server zip includes forge-1.12.2-14.23.5.2859.jar, and the panel launches it. For Minecraft 1.12.2 the panel runs Java 8 on its own.
• Memory. The pack page recommends 4 to 6 GB of RAM for a server, depending on the player load, and the pack's Linux_launch.sh uses -Xmx4G. Your plan sets the RAM, so see how much RAM a Minecraft server needs and the Minecraft plans.
• Disk space. The server zip is about 225 MB and unpacks to about 254 MB. The zip sits on your plan's disk while it unpacks, so keep room for both.
• The same pack version for players. This guide installs 2.1.3, the newest file on CurseForge, released on 14 December 2021 as a security update. Players need that version in the CurseForge app.

Install the server files

Installing a modpack reinstalls the server and replaces the current world, so use a new server or one you can wipe.

Pick the CurseForge chip in Modpacks and search for Peace of Mind. Other packs with similar names appear in the results, so check the row for Peace of Mind by TooGoodMules before you press Install. The window names Forge and Minecraft 1.12.2. When the install finishes, the Console tab reads Minecraft is installed. Press Start whenever you are ready. If you ticked Start the server when it's ready, the server starts itself about a minute later. The rest of the window (the backup, the version list and the EULA tick) is in Install a CurseForge modpack.

First start

The pack's own eula.txt already says eula=true, so the panel starts the server without opening the EULA prompt.

The pack ships a server.properties with white-list=true, so only whitelisted players and server operators can join. Open Players under Essentials and stay on the first tab, which reads Players while the whitelist is off and Whitelist once it is on. Press Add, which opens the Add to whitelist window, add your Minecraft name, and add anyone who will play. If the button at the top reads Turn whitelist on, press it once the list is ready. Whitelist players and set operators walks through it, and also shows how to make yourself an operator.

The same file sets difficulty=0, which minecraft.wiki lists as peaceful, and player-idle-timeout=30, which is Idle kick (minutes) in Config Editor and removes players who sit idle for 30 minutes.

Update the quest book

The pack's own server notes tell admins to run two commands as an operator once the server has loaded, to bring the quest book and the loot database up to the pack's version: bq_admin default load and bqs_loot default load. The notes write them with a leading slash, and the Console takes them without one. The first answers Reloaded default quest database and the second answers Reloaded default loot database.

Common problems

• A player cannot join. Check they are on the whitelist and run Peace of Mind 2.1.3 on Minecraft 1.12.2 with Forge.
• The console stops at a prompt after you install over an old world. The pack's notes say to type fml confirm in the console, wait a few minutes while the server backs up the old world, and loading carries on.
• The install window says "The backup didn't start, so nothing was changed". The window stays open, and the alert under that title gives the reason. If it is the game panel's limit on backups in 10 minutes, wait as long as it says, then hold Install and reinstall again. If every backup is protected or you are at your backup limit, open the Backups tab and delete a backup you no longer need, or remove the protection from one. Only the newest install backup stays protected: taking the next one lifts the protection from the earlier ones, so installs in a row no longer fill the slots. A backup you protected yourself keeps its protection. You can also untick Take a backup first and install without one, unless the window shows a note about your world: then the backup is required.
• The server crashes at boot. Find and read a crash report shows how to name the mod at fault.
