we already had that added prior to the issue

Ive had this many mods and more on my servers for the past 3 years and its never created this issue until now so what has changed recently that would cause this?

We're running 54 mods plus a mod pack

@mCaverylow I am the server owner and I did apply that fix and no it didnt work for ours

The only way we've got around it is if you can get a mod list for the server then save it in the launcher as a preset in the mods list. Then you can load the correct mods for the server youre trying to get into
