I believe that when you go to reply or start a new thread, the server allocates you a token, and that token expires. If you take too long (did it myself, started typing, went for a jobby, came back and continued the post), you can hit submit but you get an error message instead of the post actually going through. If you're not paying much attention, you might not notice what the lage says and assume the post went through.
What was your post about? As long as it wasn't dodgy on legal grounds, sectarianism or whatever, I doubt it would've gotten deleted. Moved and merged with an existing relevant thread, yes, but not nuked.
