After having Serana as a follower for quite some time, I have noticed she has a tendency to get a little... distracted. I've had several instances where I would turn around to check to see if she is there and she is doing something completely random. For example, when I was asking people around Dragonbridge for sightings of the Moth Priest, I had just been informed of his whereabouts by one of the guards, and I turned round to see Serana cutting wood blocks. I mean it's nice to see her wanting to help out the local community but we had FAR more pressing matters at the time.
This is only humorous to an extent of course, definitely not a big concern or anything but if anyone else has noticed something similar happen then go ahead and post it here
Also, this is my first Topic on the Bethesda Forums! I hope I fit in well with everyone...
