Serious problems post update. I'll list some of the issues I've experienced below;
1. Low-res textures
2. Random NPC deaths (3 chars in Whiterun just collapsed and died in the street!)
3. Quest not updating (e.g Arcwind Point, received word from word wall but marker not updating)
4. Strange NPC behaviour (e.g Hod in Riverwood cutting lumber in his back yard, then never leaves house)
5. Break of Dawn Quest, shade boss froze and was unkillable so could not receive Dawnbreaker.

There've been more but it's so bad it's nearly unplayable! What's going on Bethesda?
