Just a heads-up, I ran into a problem with the Waking Nightmare Quest the other day, after the 1.8 patch, which I hadn't seen on my previous character.

After you drink the potion and take the dreamwalk, any time I tried to save (Quick or through the Menu) the game would CTD. However I could save the game without issue *before* taking the dreamwalk. Actually, Skyrim runs beautifully on my PC - rock solid.

So I tried disabling all the mods, removing any trace of the SKSE, verifying the cache... Didn't help.

In the end I was forced to just console-complete this one quest and I haven't had a save issue since.
