BUG Easily Replicable - Audio Tracks 2 and 3 stop playing within 1min of Premiere Pro 15.2 opening

Doesn't seem to be an issue with that 60fps clip in 15.2 from what have tested now, or definitely didn't break in 15.2 over 5min. It shouldn't though because it is same as sequence timestamp.  

However, it's not a practical workflow to reencode hours of OBS footage daily, so a reencode isn't a fix for me. From what I understand it must be fixable and a bug as it doesn't occur prior to 15.0, am still editing fine in 14.9 with PP open for days sometimes.

OBS records ProRes using FFMPEG, and FFMPEG implementation writes timestamps in ms instead of frames/nanoseconds, OBS struggles to mux it because it has to flicker between 16-17ms a frame. That's why even though 60fps is set in OBS the file is muxed to 62.5fps. Obviously millions of people use OBS to record and this is an issue a lot of people will have from 15.0 onwards.

Also audio compression changes would require a significant recompile of OBS Studio and a huge number of changes, so that isn't alterable for anything other than directly recorded MP4 footage (which is useless to record as because if something crashes you lose all the footage as the header isn't written). 

Premiere Pro has always Vsynced to the timestamp instead of reading the framerate tag from the container. Something has changed from 15.0 onwards which means when frames are skipped it progressively loses the audio playback - presumably as part of the updates to the audio track mixer in 15.0.
