I want to remove the changes I made to many NPCs from a mod of mine, however if I set the ignore flag that creates a duplicate of the NPC and causes all sort of errors (such as one NPC turning into another). I tried to set the ignore flag on these duplicate NPC but it doesn't work.

Does anyone know if there exists a tool for Skyrim that is similair to Morrowind's Enchanted Editor? Something that would allow me to directly remove entries from the .esp.
