I have only seen this happen like three times, so I haven’t managed to drill down into what exactly triggers it, but every so often I will have a build that’s completely missing the fmod bank. Upon digging deeper in the build logs, this is what I found: ```auto ArgumentException: An item with the same key has already been added.

Either way, this causes execution of the fmod bits to stop, meaning the bank never makes it into the build. Strangely, this does not throw a big enough error to actually stop the build (though that is possibly on me?). Re-running the build without any changes fixes the issue. The game runs perfectly well in editor. It’s possible this is being triggered by building for iOS first, then android, but I can’t reproduce it that way, so maybe not. I’m running Unity 2021.3.10f1 and FMOD 2.02.07, builds run headless on a Mac. ---

Hi, Unfortunately, I was not able to replicate the issue. Could you show me your build platforms in the `FMOD -> Edit Settings -> Platform Specific` ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/2/273db973e0295aee5b19562cfc13aaab87897713.png) ---

Thank you for the screen shot. This sounds like an issue that was fixed in 2.02.09. Would it be possible to update your FMOD integration to that version or later and see if you are still experiencing the issue? ---

I’ll try it and report back if it happens again. I’d estimate it’s happened in about one in 30 builds, so it might be a while. Thank you! ---

Awesome, thank you! If you have any other questions please let me know!
