There's an issue with this version where upon performing a scan that returns a lot of results, the sounds will cut out harshly, stay out for a few seconds, then come back. When they come back, the stereo field seems kind of wrong.

I should add that before v1.3.0 the game would completely crash at this point. I wrote an automated script that would attempt to replicate this bug with a very low success rate. It helped me identify the issue and a path to eventually recover the audio process. It’s not perfect but a step forward. With the new content in the pipeline I have an opportunity to replace the treasure cues with something more stable.
