That's interesting, "Naked Nord.esp" crashed my game when I first installed it. Only after making some edits to the file was I able to use the mod. This was over two years ago so I have no memory what problem I had.
"The Mystery of the Dulan cult.esp" is NOT clean unless you're using the Replacer version provided with Better Cities.
You are right Vorians - I am using the replacer one from BC. That should be clarified in the wiki.
Let me preface this by saying that I don't understand all the details, and am just using the basic "automatic cleaning" method, which I can summarize as:
Load just the esp (and associated masters, if any) in TES4Edit, apply filter, UDR and Remove ITM, and save by closing.
Maybe some mods require special cleaning (like Gurgl reported with NakedNord.esp), that is different from the automated cleaning. Maybe I had already cleaned NakedNord earlier, and jsut forgot about it (possible, but not likely), and that is the reason why my reports differ from others.
Again, no disrespect to modders who's mods have been cleaned. It's just another pair of eyes checking your excellent work. Please do not take it negatively, that is not our intent. And I agree with Vorians that lists that make it appear serious cleaning is required are just not making things any better.
I personally suggest that any opinionated remarks be removed from the wiki for the sake of keeping it factual. Things like "needs serious cleaning" should be removed, considering that it just makes mosd seem like a bad piece of work, which they are not.
