Missing Integer in Restore File

[Anonymous]

I am working with AutoCAD Architecture 2017, and have been noticing this error popping up every time I save a file. The message says, "Missing Operation Error: Missing integer in restore file." Whether I save the file, regenerate the file, or the program auto-saves the file, this message always appears twice immediately after the command has been completed. I have used the AUDIT command and am informed that there are no errors, but the error message will appear even in the text throughout the audit test. 

It hasn't created any actual issues for me at work, (the files open and close fine, all functions seem to work, references are attached) but I'm just wondering if there is some way I can get rid of the message.

This happens in ALL files, or just one or a few?
What changed with where you store files? Something did, AFAIK the problem tends to be a corrupt DWG file that may need more than AUDIT to fix it https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/AutoCA...

Looking at that link, I think I might know the issue, but I don't have time to find the proper solution at  the moment. I think the issue might either be that the file is old (probably more than a decade in origin), or I have a corrupted block reference in the files. There are a lot of block references in the files and the files have been used for a long time from my understanding. After looking at some less used files, it would seem that not all of the files are having this issue. I will have to look into changing the files in the future in attempt of removing the issue.
