Mods Not Added to Modpack

[DeadlyDad]

If I am in the 'Manager' tab, have some mods selected, and pick 'New modpack', I expect that it will make a new modpack with my selected mods. This is not happening. The new modpack is empty. All pack.json says is

{
  "Version": 2,
  "Mods": [],
  "Modpacks": [
    {
      "Uid": 0,
      "Name": "MyMustHaves2022",
      "ModIds": [],
      "ModpackIds": []
    }
  ]
}

This is working as expected, although that is a good suggestion for a future improvement. At the moment you can select the mods and then drag and drop them into an empty region in the modpack list, that will do what you want.
