PPro CC - Timeline Audio stops working after save of any kind

Question

Guys I have a real doozy here.
PPro CC updated to latest.
I have a project that until very recently was working perfectly. Something has happened in the last 24 hours that has corrupted it and now there is no audio playback in the timeline (no audio levels registering on monitors either). If I match frame to that audio clip it plays in the source window fine. If I drag that audio clip into the timeline from the source window it plays fine UNLESS it is layered above or below one of the previously existing clips, in which case it does not work. I proceeded to do this process for every audio clip in the timeline (very tedious) and it worked fine UNTIL I saved the project. If I save and then reopen the project the newly minted clips have the same symptoms as the old ones and I am back to square one. I have now tested this process on multiple machines and every time the process is exactly the same. Replace audio, works ok, save and quit, reopen, problems.
Before I discovered the save problem here are all the other things I attempted:
If I 'Replace Footage' it does not fix the issue.
If I 'Offline Media' and then relink it does not work.
If I duplicate the sequence, the new one does not work.
If I make a completely fresh new sequence and pull old any audio clips from old timeline in, no dice.
If I make a new project and import my sequence in it does not work.
If I export the project as an XML and then try bringing that into a new project it does not work.
If I trash all renders, peak files, caches and prefs this project is still broken. I also tried doing that and then created a new XML afterward and bringing that into a new project. Nope.
If import the same audio clip from the same source location and put it in a timeline it works until I save the project, then the issue appears with it as well.
Just because I was desperate and wanted to see what would happen, exporting the clip from the timeline = no audio in export.
To be clear - the clips in the timeline HAVE waveforms visible. The tracks are not muted, soloed, sent to the wrong channels, gain turned down etc. They appear in the timeline as totally healthy and appropriate. They work fine in the source window. They work fine outside of Premiere. They work fine in old Autosave versions of the project UNTIL I save that project in any capacity. That immediately introduces this problem.
Has anyone ever seen anything like this? Is my project totally nuked? Why does Premiere continue to have these heinous error problems that ruin weeks and weeks of work in one fell swoop?
