All mods now must have their own folders for installation because it now requires the files to be named “pakchunk0-WindowsNoEditor”, so inside the ~mods, make a folder labeled the name of the mod with the marking. For example “~ssj gohan” then place the files into that folder and name them “pakchunk0-WindowsNoEditor “. 
The folder structure should be something like this: 
DRAGON BALL FighterZ/RED/Content/Paks/~mods/SSJ Gohan 
This needs to be done for every mod as of now but in testing I found them all to work. 
ADDENDUM: Each file in their respective folder needs to be named pakchunk0-WindowsNoEditor. Don't change the file extension.
