Aquamirae has a separate Fabric edition for supported Minecraft versions, with current 1.21.1 listings also showing Quilt compatibility. Treat that edition as its own loader path rather than mixing it with NeoForge or Forge files.
Fabric and Quilt context
The Fabric edition lists Minecraft 1.21.1 support and Quilt compatibility, with 7.2.10 shown as the current release when this guide was checked. Keep the loader and dependency versions aligned with the exact file you install.
Use the Fabric edition
Choose the Aquamirae file explicitly built for Fabric. A file name, release page or mod manager entry should make the loader target clear. Keep the base game version identical across the loader, mod and dependencies.
Quilt users should still verify the release
Quilt compatibility is listed for the Fabric edition, but the safest approach is still to verify the specific release and all required dependencies rather than assuming every Fabric mod behaves identically under Quilt.
Diagnose missing dependency errors first
If Fabric Loader reports a missing or incompatible dependency, solve that message before changing graphics settings or world files. Startup dependency errors are separate from in-world generation issues.
Test a copy of your world
Once the profile launches, use a copied save or fresh world to confirm generation and gameplay before opening a long-term world.
