I'm only using PG reverb on two of the audio tracks and PG peak limit on one track and on the overall output in the mixer. I don't believe I have added any plugins recently but that is a good point to check. If I let the initial slow render go until completion, then yes, the dialog box pops up asking if I want to test the file. I've let it go to completion a couple of times on different files just to see if it ever completes and it does finally finish and the file is as it should be.

I'll go back and look at my plugins to see if there is anything new that I forgot about. It really puzzles me that everything works fine if I do a save first. I changed settings on my USB drive too but that didn't seem to make a difference.
