Hi,

I finally installed Skyrim with all of the official DLCs without having too much knowledge on their specifics. I'm well into the game having reached the 14th level.

Recently I had my first vampire attack on Whiterun, however, I was not directly present. Once when exiting the city I noticed a vampire corpse, so I concluded that they must've been up to something, but obviously the guards had taken care of them. So I set out and after a few quests, when I came back to Whiterun, the real consequences of the attack struck me. Three important NPCs had died - Adrianna, Belethor and Ulfberth. At least in the case of Belethor his shop is taken over by some woman, but Warmaiden now lies empty. I went to the crypt to confirm their deaths and indeed two coffins and Ulberths burial urn were there. Now that I'm aware of this problem I use the mod 'When Vampires attack' which makes NPCs to take shelter during the attacks, however, is there any way to return these 3 NPCs so they'd function normally? I wouldn't want to reload, because as mentioned I had made quite a progress before realising the mess that happened.

Good thing you're on PC. You just have to resurrect them. Though, I hear that may cause potential problems.
