When I check Shlorg, I also used to go a little bit on north to check The Big Bad One - boss of wolves.
Here is more info about this boss:

As you can see, The Big Bad One spawns with two War Wolves, which normally don't appear in these woods.
My problem is that I often meet War Wolves without any boss! Now you probably think that somebody killed the boss and simply left War Wolves, but I always check statistics next day, and there is no The Big Bad One killed that day.
Do you know why it happens?
