I have now done the mission, Gnome Memorial Mountain: The Darkness Howls, 14 times over the last two weeks or so as of tonight. Not once has Grash spawned. I am using two real characters and two mercs. Has anyone else spawned Grash lately? I had not done this mission for about a year, but I do recall getting Grash every three or so missions. Is there some trick to it that I have forgotten?
It's RNG, when I first started GMM I had almost geared 6 toons with the drops from the chest in that mission before I saw Grash spawn, then got him twice in a row. That was a few months ago, I did run the mission again about a week ago and he spawned.
Grash took 37 mission runs to show his face to me, then every box I own got an aug within a week's time. Just the RNG curse.
Just verifying, are you looking for boss on track or manually checking the 3 spawn points? Last I was in there the boss was not marked as trackable, but you could tell if you only saw 2 of the 3 PH on track spawned.
