So after a bit more testing, most mods work, but those that have very large single files fail and the lack of capitalization by so many packagers really sucks, so either I go through and rename MANY directories with a capital letter or install in a Windows VM. It should be a requirement to have a working shift key to package a mod. Looks like I need to do the install in a Windows VM and move the data directory over... Microsoft sure has enabled sloppy techniques, jack and Jack are different words people.
