a few i have encountered (Even back at the Release of Skyrim) that have not been fixed.
The First main one that you May or May not be aware of is that after Killing a Dragon for Esbern (Blades Side-Quest)
he will ask you to get him a Dragon Bone and Scale in return for a custom Potion he will make. After you Receive the Potion
your Quest Journal does not update and still remains at "Bring a Dragon Scale and a Dragon Bone to Esbern" And if
you consume the Potion nothing Happens.
-More Bugs/Glitches-
*If Aela the Huntress is your Wife and you ask her to follow you, the Voice dialogue is broken when you Ask what she has
for Sale.
* When you Complete the Task "Bring a Follower to Delphine" the Journal does not update.
* Consistent crashing for me when i fast Travel to the Steed Stone.
*Oghma Infinium book may be used alternate times when Read on the Bookshelf interface, placed on the Bookshelf
the Taken directly from the Bookshelf, not read and Taken, and then Repeating the Process.
*Common Lag in Blackreach and Arcwind Point.

On the Brighter side i have been Loving the Dawnguard DLC and its Features that it brings, You let us craft arrows!
But now we have a Crossbow but Cannot craft Bolts!

And i would love to see a 'Fletching' Skill so instead of Smithing Bolts and Arrows, you have a knife in the Inventory, Click on Firewood
and do an Option such as 'Fletch' and it turns it into 24 Arrowshafts or Something, then chickens can be Killed for Feathers and Ingots
make Arrowheads. Clicking on the Arrowshaft or Arrowhead can bring up an Interface where the Player appears to be fletching some
wood and you can use your ingredients to create Arrows! Also this feature could be used to make Longbows and Bolts.
And New ways to obtain wood and Use The Woodcutters axe such as Chopping down Certain trees, like you can mine certain rocks.
And if you want to go all the Way a Skilltree for Woodcutting and Mining would be awesome in a future DLC.
-----------------------------------------------------------------------------
But on the Offchance that the Above will be Featured is no Problem for me, skyrim is still a Great game.
Hope those Bugs and Glitches can be Fixed in the Next pact though.
