Prior to the 1.6 update i have had two software issues with skyrim. The first was the convector glitch during "Arniel's Endeavor", and the second was a lower framerate while inside some caves.

Following the 1.6 update, legion banners have reappeared in solitude, and there are now penitus oculatus agents standing next to stormcloak officers. ( I sided with the stormcloaks) While on the road, i come across large amounts of prisoners being held by legion troops, and i rescue them everytime, but other people i come across are instantly hostile. Orc, Nord, Khajit, and Argonian no longer need to be challenged in order to fight them, roving bards draw their swords upon sighting me, and stormcloak officers come charging over the hill, warhammers drawn, with no provocation. Shadowmere has disappeared from the game, and there are three Louis Letrushes in Whiterun, with one being sunk to his torso in the ground. Dragons sometimes fly over and then continue on into the distance, and ten seconds later, i absorb a dragon soul out of the blue. All quests in solitude point me to the ground in the training courtyard, and the frame rates in caves and dungeons now often drop to 10 or 15 fps as opposed to the previous 25 or 27. Is it just the patch that has caused this, or could there be something else that has led to this happening so suddenly? If it is the patch, what's the eta on the next one?
