An question regarding the sounds in the Forest folder in the Ambient directory(SFX/Ambient/Forest):
Do these ambient sounds for 860-1 actually appear in the game or are they just there for use in an future update?(Because I was already in 860-1 several times and did not hear any of these sounds)

I haven't actually heard any of these in-game, I had the same question. I'd just assume it's a bug, it'll probably be fixed in a future update.

Finally figured out what caused this and fixed it, 2 years later.
