"A number is out of range" save issue

I have this problem constantly and it has nothing to do with file corruption.
First, my solution is simply to close and reopen the file if nothing has changed otherwise the solutions offered to retrieve and save changes have been listed in other replies.
I don't think the workarounds are actually dealing with the essential problem.
I am more interested in the cause.

In every instance for me the problem arises with the use of a file on a network drive where it remains open but I haven't done anything to the document for some minutes and then there seems to be a timeout issue (it could be as simple as not scrolling).
Is there a way of increasing the time before the programme responsed with a timeout?

It is also more likely to happen with larger than smaller documents.

Printing to PDF nor Exporting to Postscript worked for me, as the internal and external links (Contents section and internal links, as well as URLs, etc.) were all stripped from the resulting document and thus made it unusable.

Neither are a viable solution when the needed result is anything more than a simple printout or on-screen representation of one.

This is not a solution but yet another workaround.  I had this issue with a document with signature fields, so I couldn't use a fix that would strip these out.  The page export had worked for another file but not this one.  What worked for me was to combine this file with another pdf then save it.  This retained the signature fields and I just deleted the extra pages from the file I didn't need.  I was able to sign and save this file.  Ridiculous isn't it?  Not sure if there's a connection but the two files we had this issue with were created on a Windows version of Acrobat, then signed on a Mac (two separate ones) then sent on for further signature on Windows versions of Acrobat, where the issue came up.

Some authors damage their PDFs like this intentionally to deter people from modifying stuff.  But by printing to PDF then rebuilding any form fields on the document (just copy/paste them in bulk from the original), you can get around it.

Note that the Extract Pages option only works if the damage is in the document's metadata, not in a particular page.  But I'd try it first since you wouldn't have to rebuild the form fields.

Also, if your document has any buttons or underlying Javascript actions on it such as to send the data you've entered to someone, that will all be lost with print to PDF, and probably also with Extract Pages if the Javascript is at the document level.

Flattening the pages with Tools > Print Production > Flattener Preview in DC Pro worked for me.

This is just about the most counter-intuitive program I've ever used. Been using Acrobat for so many years and now I got a new Mac and have to use this horrible "upgrade." This is the second document I haven't been able to save because of this issue. None of these solutions is helping with my w9 from IRS. I should have been able to get this done in 5 minutes. 40 minutes later, still searching online and trying workarounds that aren't satisfactory. Adobe, how about just fix the software?

I was able to work around this quickly by 1) exporting the document into Microsoft word and 2) saving the word document as a pdf. However, this will only work with text only documents with minimal images. If the pdf has multiple images or an image imbedded in it, you might see issues with the spacing, margins, and weird text in the document. 

FIRST ONE DO NOT CLOSE YOUR OPENED DOCUMENT.   No.1 : Export your file as Postscript file (.ps)  No 2 : and then open it from Acrobat and save as PDF. That's it!

My solution was to 'print' the corrupted file to a .pdf. Then you can open that and use as required

What worked for me was exporting the PDF file to an image (jpeg) - this process extracted out each page as a jpeg and seems to have retained all the highlights and other nuances in the original PDF pages. I then converted the jpegs to pdfs and then merged them back into one PDF. No issues since then.
