Subclips won't attach to proxies - audio mismatch "suddenly" a problem.

This is frustrating.

I carefully spent the time and effort to import my files and create proxies. Then I selected my footage into separate bins (I don't do timeline selection as my projects are too complicated for that). I started working with my selects and I was wondering why the responsiveness to playing media was sometimes so slow. That's when i noticed that the proxy symbol wasn't in the corner (?). I looked at my source clips and the proxy symbol is there, but the subclips? - no proxy symbol. Weird. So I try and reattach my proxies to the subclips. Some attach, others I get the "audio mismatch" error. No rhyme or reason there.

Now, side note: I think Premiere should let me override the the audio issue. i don't care about te audio and I should be able to link it up anyway and if no audio shows up in the clip, I could care less. But, PP doesn't let me (arrrgghhhh)...so no solution there.

Meanwhile, I can't smoothly playback the media as I normally can with the proxies.
It has randomly just "forgotten" when the proxies are and refuses to relink them.

If I try to re-proxy the files, it just creates proxy_1 file that PP promptly ignores anyway.

As I said, frustrating.
