Sorry for the inconvenience, but I don't fiddle with LOD every day, it's just one aspect of installing a new flawless AE version, and I'm on it since more than a month, in every free minute. As far as I can tell, the Helgen farmhouses were the only LOD issue, everything else was perfect, and I had the best map ever. I really can appreciate your efforts, thank you very much.
My current DynDOLOD version is 3 Alpha 128, I don't use NG and SE, which is likely the reason why the script didn't work.
I'm trying hard to understand myself how I can get a flawless LOD, but I'm stuck with the new question of why should I use NG or SE. Are they both good, or is one an advanced version? Do I need one of it just because I don't like PapyrusUtil(which isn't the case), or because it's faster, or because it can deal better with large reference bugs? I can't tell by the description on the mod pages, and both aren't mentioned as a requirement on the DyDOLOD mod page.
