Asset file deleted on Android build

Hey folks,

I'm experiencing a very strange problem here. One of my soundbank files is deleted from disk any time I attempt to build my project for Android (thus causing the build to fail). Dice.bnk is in Assets/StreamingAssets/Audio/GeneratedSoundBanks/Android after I generate my soundbanks (I'm using Wwise). When I switch back to Unity it sees it and creates a .meta file for it and all is well until I go to build, at which point the file is deleted (confirmed with a shell window). Unity still thinks the file is there until I refresh the folder, at which point it notices it is gone and gives the warning about deleting files without deleting .meta files.

I have another soundbank file in the same folder that is not being deleted.

I successfully built the project a few days ago, and as far as I can tell, the only changes between then and now are scripting changes; I don't believe I've mucked around with anything that would affect the build.

I'm using Unity 2018.3.6f1. Does anybody else have this problem? Does anybody know why this file is being deleted?

Thanks in advance.

 

An update:

I managed to get this working by using the Wwise Picker window's "Generate SoundBanks" button instead of generating soundbanks through the Wwise application.

However, this problem is back, and no amount of regenerating sound banks through the Wwise app or through the Wwise Picker window is helping.

If anybody has any bright ideas, I'm all ears (eyes?).

 

I'm facing the same problem, the copied soundbank is deleted after build.
Did you find a solution for Android build yet?
