Pack setup

Use OptimumFuse 1.14.0-beta.5+fabric.1.21.3 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

The selected pack release is OptimumFuse 1.14.0-beta.5+fabric.1.21.3. That file is for Minecraft 1.21.3 with Fabric 0.16.9. It contains 121 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod.
