I noticed that quests from each chapter of the game drop away when you move to the next chapter. This is unfortunate, since often you have to use the on-screen "Proceed" command, and you are then in the next chapter.
When I went back to a prior chapter, quests had gone missing and I had to re-acquire them and run through already-completed zones to complete the quests.
I am still not sure how to do the Truesilver quest playing as Andriel. If the mithril appears so early in Gundabad how do you switch to the dwarf? When do you switch?
I have had no glitches until last night, when I encountered the turrets not working in Legendary.
On the idea of quitting methods, one thing I have never varied is how I quit my play session. I have always waited for a save, then exited the game, and upon returning to the main WITN menu, I use my PS controller to shut down the PS3, without actually quitting WITN first. I completed Normal and Heroic with no glitches. Only on Legendary, early in Fornost, have I encountered a glitch. And it's a damned difficult one to deal with when dozens of sappers are pouring up the stairs and the turret doesn't fire...
