However, it has come to my attention that some mods are not supposed to be cleaned in order for them to work properly, though I have never experienced any problems with it in the past. A good question to ask I suppose is, is it a good idea to clean the official patch project ESM? No GMSTs are found but several hundred objects are. I assume that this simply reduces it's effectiveness as a patch, but I am not sure. Is it generally safe to just clean everything, or not so much?
