[BUG] Mod updates stuck; infinite loading bar.

[Konglomneshued]

Describe the bug
Happens 99% of the time I try to update mods. It will just sit there and not complete the update. It downloads an empty jar file which I have to delete or my Minecraft will crash at launch.

When updating Fabric api from 50.0 to 51.1

Unkown error during the update process: xyz.deathsgun.modmanager.api.http.HttpClient$InvalidStatusCodeException: Received invalid status code: 403

Here is the error in my log

I don't have Cloudflare (in fact I didn't know what that is until now) but I still have the same problem.
Edit: The problem auto-solved itself.

Will be fixed with Core#1
