In the old UI, it was super easy to not press the correct save button. This is why this text was suggested:

"If you can't find how to edit your sound here's a little visual guide:\n"

I tested the process and found it might still be unclear to beginners, at least the part of getting from a ticket to the sound page.

Please replace the URL with

Feel free to take these screenshots (I made them with a test account) and do anything with them, including editing, joining, hosting on your site.

One could also add an edit link that is only clickable for the owner to the sound related to the ticket. to ease the editing.
