unwanted layer merge
Computer 1 creates a file with 4 layers (Print, reg marks, thru-cut, crease)
Computer 2 opens file and all layers have been merged onto 1 single layer. In fact the other layers don't even exist anymore. Also everything in the merged layer has a clipping mask over it?
Yet when computer 1 opens the file again all the layers are still there.
Same versions of illustrator on computers 1 & 2.
Jan, thanks for the update.
Hate these inconsistencies! I really hope the team can look into it and find a solution. I doubt though they can dig in without the file, so I assume you found a way to share with the them anyway.
Please reply if you have some news and don’t hesitate to redirect folks who have the same problem here — perhaps they have a file they can share.

Egor, thank you for your time. We receive the artwork from our client in the same manner for over 15 years. The way they save and send the documents will not change. They would have to change it globaly, which is impossible to do at this time. We checked the pdf file on 3 identical computers (same model, same OS, same Ai version) two computers merge the layers, one computer opens it properly.
Yesterday, I had over 45 minutes online call with Adobe support, trying to figure it out, sharing screens, testing the file on both Mac and PC etc with no result. At the end it has been passed on to Adobe engeneering to figure it out. We will see next week if there is a solution.
I also checked other forums on the web and there are other people struggling with the same issue.
I also cannot share the file as the content is highly confidential.
Jan, in this case, no wonder.
If a user saves a PDF-file without the 'Ai compatibility option' (and some PDF presets don’t have this option included by default), Ai has no layers to read back. So you might want to check if your client keeps this option when saving files.
The problem might be in version differences. Are you sure you use the most recent Ai version, the same as your client?

@egor I did not create the pdf, we get the global artworks from our client to adapt it. Yes, it is Ai saved into pdf. Yes, it fails to read back the original Ai. I am in contact with Adobe support. They are working on it, but so far they have no idea what to do with it. I cleaned up my comp and reinstalled Ai with no result.
Jan, what format do you use to save the document?
I suspect you are using PDF format to save it, and for some reason the computer #2 fails to read back the original Ai-component of the PDF and falls back to importing the PDF-component of it, which obviously leads to flattening it.
