Having failed to figure out why the thing just breaks when I edit the costs in Notepad and Notepad + I downloaded the Pack Editor for Total War Warhammer 2 to take a look at the thing there to see if I could figure it out, a bit of testing with the base file revelaed nothing that I understood, though I got the following error when I opened a copy where I had edited the costs of the traits in Notepad and notepad+

Failed to open vanish_clc_character_trait_levels.loc:
System.IO.FileLoadException:Illegal loc file: doesn't have a byte order
mark
at Filetypes.LocCodec.Decode(Stream stream)
at Filetypes.PackedFileEditor`1.ser_CurrentPackedFile(PackedFile value)
at
PackFileManager.PackFileManagerForm.OpenPackedFile(IPackedFileEdit
or editor, PackedFile packedfile)

this error repeats for every entry in the Text heading when opening the .pack file in the Pack Editor after editing the costs in Notepad+, the only diffrence is the name of the selected heading appearing where vanish_clc_character_crait_levels.loc is in the example above.

While I personally have no clue what this means hopefully it will be of use to anyone else trying to edit this Mod for their peronal enjoyent as well as help teh developer figure out whats going on.
