XF 1.3 Google crawl error - thread # not correct?

[tommydamic68]

This is really strange, I have had this thread since November 3rd 2013. It is here and working http://sphynxlair.com/community/threads/sphynx-pooping-or-peeing-outside-the-litter-box.24319/
However, checking Google webmaster tools I found a crawl error and when clicking this error link I found the typical error page. Here is what is weird, the read number on the error page is off by one number, how is that? http://sphynxlair.com/community/threads/sphynx-pooping-or-peeing-outside-the-litter-box.24318/

Sounds like someone either posted a link that was wrong or that thread existed and has since been deleted (it could have been a redirect).

So your saying the link was perhaps from another location then the source perhaps, my site? The thread does exist as verified clicking the link above. A fix - or concern @Mike?

There is no 'fix'.

The URL was indexed by Google because the URL existed at some point.

I guess @Brogan what I meant by a 'fix' was I had had issues- serious issues coming over to Xenforo from Vbulletin with redirects that @Mike had helped me with. I just wanted to ensure there were not concerns with redirect issues again.
