"pack_identifier" is being filled in with "pack_author" info

[toontownlpz]

This appears to be the cause for my AI softlocks, as pack_identifier supposedly needs to be unique, but every pack I've built has filled pack_identifier with "louiepicklezilla" when I set pack_author to "Louie Picklezilla".

{
    "pack_name": "Independent Downsizer",
    "pack_author": "Louie Picklezilla",
    "datapacks_version": 100,
    "pack_identifier": "louiepicklezilla"
}
