About this Modpack
Summary

You can build machines that can allow you to take control of the world or embrace nature and magic to integrate yourself into the world and its biomes. Quantum Freedom's philosophy is that one mod for one use, which helps keep the pack light by not including mods without a reason for them, they are all carefully chosen to help keep resource usage low, while having a fun modded experience. Quantum Freedom is about having fun in a modded environment. A minimal stress modpack, just kickback and relax with friends!

Frequently Asked Questions
Quantum Freedom 3 server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 10 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.
How much RAM does a Quantum Freedom 3 server really need?
Minimum 6 GB, recommended 10 GB for stable performance. per 4 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €7.800000000000001/month).
Can I add custom mods to Quantum Freedom 3 without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.1.2). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
Quantum Freedom 3 server lagging – performance tips
1) Increase RAM to 10 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time.
