@djh269 Are you sure it's gff files? I compare an unedited copy of Baseitems.2da and my Baseitems.2da and I get an error message saying "Invalid file version. Loaded file is not in GFF V 3.2 format!"
That's because a 2DA file isn't a GFF file. It's a 2DA file. You can also compare two different 2DA files in ChangeEdit and it will automatically generate any differences in the changes file.
@DarthTyren you're completely right, apologies N_DReW25 for the oversight. I did try using another's template with the Jolees Hut mod, and failed miserably, Fairstrides pointed me out to the compare function and it's worked every time. Once again apologies for the GFF/2DA oversight.
