I was able to go "back in browser history" previously; that's where I got a "copy of the origin text". However, that tab is no longer available, so I can't do a reload. I sought advice, rather than just doing this earler, as there may have been a more serious problem.

So, I pulled up the original "[OT] Merry Christmas and gift of love" and replied with my saved text. Preview: all good; Create: all good; Updated thread: all good.

If the original appears at some point it the future, it can be deleted immediately as a duplicate. Thanks for your help with this.
