Yukon.
I think it was a glitch.
First, I never have Moose in herds like Wapitis, they walk alone. And the charge bonly when beign attacked before, I think it were simple random collisions that the game produces so happily and often.
Second, the Wolves, staying around
all day and making noise, but soon being invisible again? They probbaly were gone ,a dn the echo sound stayed.
There have been sound bugs before in the game's history.
Anyway, it was a tale to tell, I think.
I will never go sleeping and saving again without having uploaded ammo first...
