I've gone and done a huge search for your thread like Tren did. I've also looked at all locked and hidden threads. I came up blank. If it was hidden or locked I or Tren would have seen it.
Like Tren has said the chances are it's gone off page 50 and if thats happened it's gone for good. Not even Himself can being that back.
Even the search on Google I did I found the Quick Find Code. So it's not looking too good. With Google they Cache the pages for a while and even the Cache did not show so it's looking like it's gone from the forums for a good while.
According to Google you last posted on it 29 Mar 2015. This was the Quick Find Code for your thread 194-195-746-65487886 Even using that shows nothing.
I think for now it's best left. Removing it now might cause more issues then it resolves.
I could tidy up the thread and remove a few posts but it could cause more issues. So for now the thread will be watched and if anything needs doing it will be done.
