Just a heads up. the user_aliases.csv appears to be on automatic update on steam....so you might want to take incremental backups of it. I woke up this morning and all my sounds were gone. The file was replaced with the default file with the test sound in it :-/

Mine have never been wiped. They are still there since I first added them about a week ago.

I think it happened when I deleted the directory \Call of Duty Black Ops III\sound_assets\tst
now the directory is back with the wav file in it again.

For some reason I can't message you. I'm working on a map and wanted to know if you can work with me on some scripting?

It only gets replaced if you verify the cache for the tools.
