In response to post #24687944. Basically building a new game from scratch! Very very interesting! I always thought a game like Skyrim is the best possible game ever but it had to be rebuild again to address papyrus problems and memory-related problems. Having a more stable game would be just the paradise for a modding comunity. We could create our own game looking at the manpower displayed in creating DLC-like mods!
In response to post #24681829. #24686464, #24687639, #24689534, #24690734 are all replies on the same post. I have 300 mods. If I did have to pay 1 dollar for each one of them I'd quit playing Skyrim in no time.
Guys my problem was the werewolf mastery: disabling it using the configuration ring that comes with the mod instantly made vampires hostile again! Hope this will help more people!
