Help with lost keymaster asset!

On my server, I use a custom-made uniform pack for the police, which I had made exclusively. I added it to the assets for Tebex protection on my own uniforms.

However, I lost the original file, and I only have it in the assets on Keymaster. If I download it from the assets, add more items (new uniforms to add), and upload everything to the assets again, will it cause any bugs?

The author doesn’t want to send it again.

If the files are encrypted and you reupload the files it would break because you would be encrypting encrypted assets…
