More disappearing comments. Answered
It's been reported many times, by many people, but the "disappearing post" bug is alive and well.
It's happened to me quite a few times today, on individual instructables, forum topics and the answers section.
They don't appear later on, or appear only for my eyes, they simply cease to exist as soon as I hit "post".
When I have spent some time writing a long post full of relevant, useful links, this is a very, very annoying bug.
