Audio clips (narrations) are playing on the wrong slide(s)

Hi everyone. If you're experiencing this issue, the ONLY reliable solution is to import your entire project into a new file. Trust me on this. I've spent hours with this error.

No, reloading the audio file will not fix it. 

No, playing the audio a bit in the timeline editor and saving it will not *always* fix it (I've noticed this sometimes fixes the slide in question but breaks another slide elsewhere, which is hard to detect if you have a course with ~250-300 slides). 

Luckily, the import feature will carry over all of your content, triggers, and slide settings. All you will need to do is A) set your player size to match your old file, B) File > Import > SL> Choose your file, and C) re-adjust your player settings to match the old file. 

P.S. It's disappointing that this issue has persisted for nearly 6 years without an update patch from the SL development team...
