Hi, I wanted to add desolation to my server which is run on quilt and 1.20.1. I wanted to add it in to the pack after I had checked the previous mods all were working and not causing a problem. however, when trying to start up the server with desolation it crashed and told me I needed fabricloader. If you can help me wish this issue I would definitely appreciate it :)

Sorry; this answer is pretty late. Desolation for 1.20.1 requires Fabric Loader version 0.14.25 or newer. The Quilt Loader you were using only provides 0.14.24. I'm not sure how to tell what version of Quilt Loader is required; their changelog does not seem to show what version of Fabric Loader each Quilt Loader provides.

-- Error 1 --

Desolation requires version [0.14.25, ∞) of fabricloader, which is missing!
