I'm seriously getting annoyed at having vampires spawn at whiterun's gate (since whiterun is the main town I spend time in) and killing a shopkeeper or two (and other random NPC's), forcing me to reload a saved game and rushing to the gate (sometimes all the way from dragonreach) just to ensure they get killed before they can do any harm. It would be different if they only focused on the guards, but no, they kill anything in their path.
Sure, the idea is rather interesting to have vampires randomly attack towns and such, but not when it causes more issues and annoyances than fun. It's getting to the point where I'm considering only entering town during the day so I can avoid the issue, but that's just a huge hassle.
Anyone else getting annoyed at this?

It's even more annoying than a challenger spawning with fireball spell in the middle of a city.
