That happens sometimes. But your comment is probably still floating around here somewhere. If you contact the support people, they may be able to get it posted.
It seems to happen to me a lot when I take a long time typing, but not every time. I don’t really understand it, but but I do understand the frustration. It did it to me awhile ago when I had spent close to an hour researching a response for someone. It will also happen sometimes if you did something that looks suspiciously like spam, like copy and paste a lot of stuff or put a lot of links in you post.
Anyway, I hope you understand my comment wasn’t personal. It was just an interesting little thought that popped into my head. So don’t feel like you have to post the details, but share if you want to.REPORT ABUSE
