I have the latest patch as well as Dawnguard and Hearthfires installed. I held off on doing the main questline until I reached level 81. After that I decided, "what the hey" and started maliciously attacking the main questline and went as far as beginning "The Fallen". I also did a bunch of Arngeir's word wall quests just before reaching that quest. So, I have a bunch of dragon shout words known, but not unlocked. Figured I'd run around, do some other quests, etc, but no dragons spawn. On a previous character (which I stopped playing because of a Blood on the Ice bug) I would encounter dragons everywhere, not just dragon mounds or word walls. I'd encounter them in Riverwood, Dawnstar, College of Winterhold, Solitude (in the city), out in the wild, etc. Now, it seems that if I visit a dragon mound that I never found... no problem, there will be a dragon, but when i revisit word walls, when I walk around for hours on end, when I fast travel from place to place to place, no spawns. Nothing. Granted, before it seemed a bit much, but then again... dragon attacks are supposed to be off the hook... and I'm just encountering a rather quiet Skyrim. I've tried a bunch of things to attempt a fix, but to no avail - the only thing I haven't tried is reinstalling the game all over again. Any other suggestions?
