Makes quests static: actors you fight with and against (them and their inventories) not nuisance beasts (i.e. rats and mud crabs). Traps, locks, rewards, contents of quest-specific containers and boss containers in quest locations.
This means that if you find a quest too difficult, you can fall back and improve your character and return, knowing that the enemies will not have become magically stronger. Also any enemies you've already killed will not magically reappear.
Currently for vanilla, Mehrunes Razor, Orrey and Thieves Den. Will be extended to SI, Fighters Stronghold and Knights of the Nine. I aim to be compatible with my current load order, though will take requests for compat. with other popular mods later.
Progress: In final stages of testing.
