Just a quick question, i just bought dawnguard but didn't have any old saves of high level characters having not played in a while, i got to level ten and suddenly vampire attacks started, only problem is they killed my npc's, Belethor is a (well-deserved) pile of dust and skulvar sable-hilt won't be needing his horse-pooh raker where he's gone, only problem is, i don't really want them dead.
Are they being killed because i am low level and citizens are possibly weaker at level 10? Should i turn off dawnguard till i reach a very high level, would that improve citizen's chances of survival? Or are they going to get killed all over the place no matter what level i am? Am i wrong in thinking that passive citizen's level up at all?
Also, another curious thing is that Ysolda (Nord lady that asks you to get her a mammoth tusk) seems to have taken over Belethor's shop, now that would be great, except when i talk tto her and choose "ehat do you have for sale" the menu comes up, both hers and mine are totally empty, no transactions can be made yet she has about 800 gold.
Any advice would be much appreciated.
