GMPublisher not uploading sound files (.mp3 and .wav)

[revvze]

GMPublisher doesn't detect sound files despite them being in the folder that is being uploaded to the workshop. I have taken down the addon, uploaded a completely new one, changed folder name and structure multiple times, nothing is working.

Please tell me how to fix this or fix this issue, thanks

Does the problem still occur if you use gmpublish to publish, rather than gmpublisher?
