@sheson: I'm glad that worked for vram1974, but it did not work for me. I hope you can help me. I'll make my bug report as follows: Had a previous version working 2 days ago (on MO), then upgraded to the August 1st release of 1.41.I intended to do a clean install so I reinstalled Papyrus (2.8), TES5edit (3.1.1), and removed all of the previous version of DynDOLOD.Followed the usual build instructions from your site: and got .json does not belong to this DynDOLOD.esp, for the Tamriel world file. Quoted: "DynDOLOD_Tamriel.json does not belong to this Dyndolod.esp"Rebuilt it several times, with additional attention paid to making sure that the files were getting copied correctly, and the output was being moved correctly.Came onto this forum, and checked out the latest advice from you for dealing with similar sounding problems, hit upon your message to vram1974 above.Checked all of the Bunch of Numbers you told him to validate here: https://forum.step-project.com/topic/5011-dynamic-distant-objects-lod-dyndolod-141/page-127?do=findComment&comment=135776All of the numbers were identical, including all the ones I checked in the TES5Edit log.Reruning the script produces identical results each time. I have replicated it three times from scratch now, including intermediate cleanings. So what should I do? Thanks in advance, -potatobaron
