The background music has been working fine right up until I opened a jar to whistle for fireflies in Fjarcke. I expected it to restart when the jar closed, but it didn't. Nor has the music restarted on changing streets. I am now going to reload to see if the music comes back.
using IE8
Edit: Music returned after reloading
Updated: same happened a second time I tried it. I'm also finding that other sounds such as the scraping of barnacles and shovelling of peat have gone. On the other hand the noise the barnacle makes when detaching is still there.
