I've been trying to get this soundset to upload for 2 weeks. The log says it goes all the way to 100% but it never shows up in my campaigns. ive tried copying it, changing the name and everything i can think of. My last try and the most updated one is called "wave echo cave again"
Maybe export a zip (the little save button on the title row of the SoundSet inspector) and share that with me, and I'll look into it.
Hadn't had a chance to go back and look at it until yesterday and some of them showed up so it's all set
