What is the flute music for when in the frontier?
Solution 1:
When the flute is played there is some unusual animal event happening near you. Examples I have seen so far;
- Two deer bucks fighting
- A wolf pack
- A bear with cubs
- A deer with children
Sometimes it can be difficult to see, and sometimes you may have scared off the animal that caused the alert. But it's happened enough times for me to be pretty certain this is it.
A sidenote; I think I heard a different flute note once and just after I was attacked by a wolfpack. Could be that it was signalling danger?
