I was just posting my first comment, i noticed i wanted to add something and thus edited it, saved. Worked good, then i saw another minor change i wanted to perform, edited again and saved again (all within a minute's time). Now after the last save the post just completely disappeared from the discussion... Luckily i had copied most of the text (it was a long post) to my clipboard. But it was strange to see it disappear. I've not tried to reproduce the issue.
Edit: I also tried to reload the page then, no change. Went back to google page where i found the discussion. Went forward to it again. and now the previous reply i was typing showed up, which already disappeared the first time. And thus not the one i was working on last. Bit confusing everything.
