I cleaned it. It removed duplicates to the master and did the "undelete and disable" thing. WTF? Doesn't Bethesda have the means to release a clean DLC? I find it irritating that after all these years (I had to clean all the Oblivion DLCs too) that they haven't figured this out yet.

Thank Talos that there are programmer/players that are smarter than they are!!!

..Not sure I wanna mess with the ESM file.

Since it doesn't affect anyone other than those who choose to mod their game, I guess they just don't see it as a priority.
