First, Unfathomable Depths was bugged and I couldn't complete the quest, reload older save and go back and try it again, same result. Find a way to edit Bethesda's script so I can finish the quest. Go to my house in Whiterun, find out that the weapons racks and plaques no longer work, reload before Unfathomable Depths to see if they were working, they were, reload before I finished Unfanthomable Depths and decide to just skip that quest as it seems to hose up too much. Move on with life and go to a misc quest at Dragontooth Crater. Kill the dragon, no soul absorbed, walk up to the wall, music is playing, the animation starts, but I can't get the word of power. Reload older save, try again, same results....
I have had more issues but this last stretch is it. I spend all my time replaying things just to avoid bugs. Sorry, don't have time for that any longer. This very well could be my last TES game which is hard to say because when it was working early on, I loved it. Thought it was the best thing since Morrowind, but now at level 34, it's just a buggy mess no longer worth my time.
