HI @Anonymous,
We had taken your issue offline for a bit. I found that when I verified all the xrefs to be mapped (so that they could be found, although I admit that I missed one, that they did show yup in the PDF. You indicated that normally you work with Google File Stream. I have seen many such issues with that service and to resolve them you would have to visit their support pages.
Although, you did indicate you tried it locally. You told me your OS is High Sierra 10.12.6 but that is actually Sierra. Is it possible for you to move to High Sierra 10.13.3 to see if your errors persist?
Another test is to move all the files to one folder instead of subfolders to see if that makes a difference. I suggest that you place this folder on your desktop for testing. In one of your emails, I believe you also mentioned that you were using a PC3 from Windows and perhaps a CTB and well. Can we remove those from this test and see if that also improves this behavior?
