Is there an event involving a waterwell?
I was quite sure I've heard the music and there was nothing but a well in my viewing range and around, but it can be quite confusing since some pieces of ingame music are louder than others and they can change dramatically, additionally I am listening to audiobooks with sound effects while playing (I turned on ingame music in the first place because I didn't hear any special sound when I found my first bunch of carts, so I was wondering if this is a requirement). I tried to do a few things with this well, but nothing unusual happened.
So, am I hearing things?
