Reliable mod that prevents random attacks in cities?
Specifics:
-Shouldn't interfere with scripted/storyline combat (example, the Forsworn at the meat stall in Markarth) or combat that the player starts.
-Avoid use of scripts. Must be compatible with existing save files.
-100% reliable, assuming there aren't any mod conflicts.
-Only has to prevent random monster attacks specifically on cities, towns, and other populated areas (this means that the player can lure monsters to towns).
-Minimal configurations. I tested the "Timing is Everything" mod and it was too convoluted with too many exceptions. Just remove the offending encounter zones with minimum of fuss. If there's a config, it shouldn't be any more than picking which areas to enable/disable.
The most prominent monster attacks on towns to prevent would be vampires and dragons.
