"Edit" resulted in deleted post

I clicked Edit to add to existing post and nothing happened - clicked it again and got something like "Sorry, that was unexpected, it's been reported"... but the existing post had disappeared.  It was quite long, too :'(

Just in case this was my fault (but I don't think it was) I would like to repeat the plea that EDIT should be separated from Report Spam and Delete.
