Two minor "bugs?" I've discovered while playing so far.
When everyone get's turned to stone, this guard does not, http://i.imgur.com/O604EPa.png
These two didn't either http://i.imgur.com/dJR14EF.png
(Also, shouldn't the bridge trolls also be turned to stone during this time?)
This one's somewhat nasty.
Start here at the springs http://i.imgur.com/hkoI0XK.png
Swim down from either of the water spots except for the one you came from http://i.imgur.com/vmnyyyE.png
You end up here http://i.imgur.com/0t3RlNg.png
Swim back up http://i.imgur.com/VWlG5Bh.png
And now you're permanently stuck. Reload last save. :(
I don't ever recall opening this chest seeing as I needed flight before I could open it, but when I flew over it was already empty. http://i.imgur.com/2EUSxz5.png
"Bug?" Fog persists in within these two zones after the vampires have cleared out. No fog left otherwise except when using the teleport. The main area then is then temporarily covered in fog once again until you exit the zone and come back in. http://i.imgur.com/Mt0PV7o.png http://i.imgur.com/CMzqNT8.png
