I answered this question wrong, which took away some progress. Then I pressed the show solution button, and got the first hint, which didn't take away any progress.
However, because I was using Opera, and the "next hint" button does't appear in Opera (fix this bug, please) I opened the page in Chrome, and clicked the hint button. As a result, I lost progress again.
To see what was going on here, I reloaded the page (in Chrome) and click show hint, and again it took away progress!
I thought answering wrong and showing the answer by hints should take away progress just once.
