Modpack Version
v.18

Minecraft Version
1.19.2

Describe the crash or bug
It appears that the modpack contains a few 1.20 mods, even though it is running 1.19.2.

Steps to reproduce the behavior:
Download the server files and run them (should also happen on the client)

Expected behavior
The server should start

Ah, the issue is not that it contains 1.20 mods, its that Fabric Loader is still on the older version for Server Start. You need version 0.15.10. Go to server_files/settings config, and change both call outs to "0.14.25" to "0.15.10"

I will release a update for the server pack

Released fix in curseforge
