I recently tried to clean some mods. No manual cleaning just some ITMs and UDRs. However my game crashed while loading up when I was using the cleaned plugin. Is this a known problem of FNVEdit? I used the latest version. Oh plugin was OperationFixedTerrain.esp, but it really happens with any other plugin as well.

Turns out I can clean ITM records. UDR cleaning was the culprit here. More information on that case (or a new NVEdit version ) is appreciated, though.

e: Apparently DLCs don't like being cleaned of ITM records.

Yea, don't clean the official DLC, I learned that with Fallout 3.
