That’s because the download itself is indeed in a .rar format, although the changes seem to happen just fine for me. I even tested it out with the lycanroc by making sure my version is alphabetically later than the MFR pak file and it seemed to work fine, even replacing the descriptions for the ‘armors’ with the unique ones I wrote up in the latest version. I can only assume you have yet another version of the lyceen that overrites both the MFR version and the one Glasscannon posted…or something, I dunno.
…And hey, may as well make the most of this post while I can instead of making a separate one. I posted in great detail about it over here already, but I’ve added support for the Sangheili but with the male fat body type only for both genders, soon to include the female variant based of the results I got in the poll. I’ve already posted a preview there but have one here too if you just want the link from here, I don’t mind!
Have fun with them for now until I update them hopefully soon!
