In the bird-watcher concept exercise the hints do not get displayed.
There should be an actual hint (as you can see in the markdown file on GitHub) but each hint only shows the heading.
How to reproduce:
Go to the online editor, click on the instructions tab, scroll down to the tasks and click on one of the “Stuck? Reveal Hints” buttons.
@angelikatyborska thought it might have something to do with a missing ## General
section.
Edit: @MatthijsBlom is probably correct, the hints in the Markdown file are not numbered.
Edit #2: Fixed by @porkostomus. That was quick, thank you very much.
