Update instructions

Disclaimers

  • As with any update, things may break. Probably not due to Fabulously Optimized, but maybe your launcher, your custom mods or your hard drive. If worried, make backups.
  • Upgrades from stable to unstable (alpha, beta) versions are never supported (make a separate instance!), while updates from unstable versions to stable ones are.
  • Any kind of instance downgrading is never supported. Make a separate old instance or use something like ViaFabric if your server hasn't updated yet.
  • If you follow these instructions properly, all custom mods and most mod settings you have will persist. If you want, you can reset your settings to get the latest changes.

Minecraft Launcher (vanilla)

Currently the only way to update is to "reinstall" the pack. Consider installing a different launcher for a smoother upgrade experience.
  1. 1.
    Download and install Fabric Loader version 0.14.12
    • Older versions of the modpack - 1.12.3, 2.7.3 and 3.14.1 require the use of Fabric Loader 0.14.12 instead.
    • Remember that the installer version doesn't matter, what matters is the loader version that appears when you run the installer.
  2. 2.
    Open Minecraft Launcher, click Installations and then click 📂 on the Fabric installation
  3. 3.
    Delete all files in mods folder
  4. 4.
    Go to Files on CurseForge
  5. 5.
    Click Download the latest MultiMC version of the pack
    • Click the title of the CurseForge version you need and scroll down, you'll find the MultiMC variant there.
      • Alternatively, look for it in the sidebar, under "server packs".
    • If you don't see any mods inside the zip or only see one, you downloaded the wrong version.
  6. 6.
    Open the zip file, go to Fabulously Optimized x.x.x > .minecraft
  7. 7.
    Copy all folders from zip's .minecraft folder to your .minecraft folder; if asked - replace the files
  8. 8.
    If you want FO default settings as well, delete options.txt (your vanilla options will be reset)
  9. 9.
    Launch the installed Fabric profile
  10. 10.
    If you now see "Fabulously Optimized" in the right bottom corner and its version number is newer than before, you're done!

Resetting settings

Because the pack is using YOSBR, your vanilla options and most of the mod ones will not change when you upgrade, despite what is stated in the changelog. This is made so that you can upgrade without having to reconfigure your options all the time.
However, at some point you may still want to do that in order to get the latest changes. So:
  1. 1.
    Open the modpack folder
    • CurseForge Launcher: right click on the modpack tile → Open Folder
    • MultiMC: right click on the instance → Minecraft Folder
    • Prism Launcher: right click on the instance → Folder → .minecraft
    • GDLauncher: right click on the instance → Open Folder
    • Vanilla launcher: go to Installations tab → hover on the instance → click 📁
  2. 2.
    Delete the config folder
    • If you prefer, also delete options.txt which stores vanilla options
  3. 4.
    Rename the file to pack.zip
  4. 5.
    Open the file you renamed, go to overrides
  5. 6.
    Copy/extract the folder configs out to the modpack folder you previously opened
    • You may delete the pack.zip after you're done
  6. 7.
    Launch the game. Modpack's defaults are now applied!
