I have a theory of why that might be happening...
Did, as any part of your workflow, you save a PDF file?
There's a sequence of operations that can result in the setting for the [ ] Layers checkbox in the Save dialog to be turned off, which can indirecty result in a later save causing the saved document to be flattened.
Double check your [ ] Layers checkbox when doing a Save As operation.
It's a setting that almost never gets changed, so we tend to ignore it.
After further testing, I think that is exactly what's happening. I know I saved at least some of those files as pdfs at some point. I'll have to remember to double check that box from now on. Thank you, Noel. You're a great help.
Noel, I'm bumping this old thread after someone asked the same question. I've had this happen to me twice. The first time I thought I must have messed up somehow, but the sencond time, (with work for the same clients from hell) I was completely sure I had done it right, and then I remembered turning off the layers option in the PDF file that went to the printer, before finally saving out the layered PSD file. It was a fair bit of work, and I had to do some of it again because I needed the background for another advert.
All part of life's learning process, and I have mentioned the benefit of periodically savinf big projects with sequential names, when people have complained about lost work on this forum. I guess even as single person businesses, we should try to addopt a sort of ISO9000 best practice, or elements there of at least. It has been life saving having access to all my data while my big system box was out of commission. Easily worth the price of Shadow Protect and a few external drives. I got the big box back today, so happy days...
I hope this helps people.
Glad you got your computer up and running again, Trevor. I know how lost I'd be without mine.
It's appalling that people are taking this lightly. I rarely save PDF because I'm not a Graphic Designer so I tend to forget after that amount of time this absolutely stupid feature! It is hours of work lost as I have to redo the entire thing to make it editable again. Why would I want to Save as pdf and then have my file switched to PDF? Isn't the use case for most users that you would have an editable Photoshop file and just save a PDF when you are done? and go back to the psd and choose to save again if that's the case? why would I flatten layers? This boils my blood, so much work wasted with a software that costs so much

Well, ideally layouts that include text and graphics would be done in Indesign or Illustrator, but if one has to create the montage in psd for whatever reason then: Yes, a layered psd, tif or psb and a pdf copy would be a proper approach.
But if users forget to check »As a Copy« when saving the pdf that is not Adobe’s direct doing, is it?

Adobe cannot prevent all possible user mistakes; though I concede that this issue has come up so often that it should merit some additional alert or dialog/interface change to make it less likely to happen.
