I found one mod using TES5Edit that came up with "LOOKUP FAILED!" with regards to Tamriel, but it's not one that I've added or updated recently: Dovahkiin Relaxes Too. A second Tamriel in Dyn hasn't come up before now and the FormID is still 0000003C though. Attached is my TES5Edit_log file. TES5Edit_log.7z

I've run into an issue since updating DynDOLOD and adding a few other mods: When generating 'DynDOLOD - Worlds' I get options for two Tamriels. One is "Tamriel (Skyrim)" as always and the other is "Tamriel (LOOKUP FAILED!)". When I first installed I hit Select All. This led to the "could not find json" error so I exited the game and tried to re-install Dyn. The second time I installed I hit Select All and unchecked "Tamriel (LOOKUP FAILED!)". No error this time. However I noticed significantly more stuttering and pop-in than usual when DynDOLOD is active. Grass pop-in was particularly bad. It was the same upon reload. The MCM said Dyn was active but I don't think it was working right. I suspect it's this second 'Tamriel' that's causing the issue, even if LOD isn't being generated for it. Any idea what's causing the issue? The new mods are: 'Smelters for Riften and Solitude', 'Immersive Dawnguard Dayspring Pass', 'Windhelm Lighthouse', 'High Hrothgar Overhaul', 'Sky Haven Temple Merchants and More' and the Enemy AI and Enemy Scaling modules from Skyrim Redone (I doubt this one could be causing the issue). Possibly of note is that of the above mods, only the 'Smelters' mod is listed as a Master for the DynDOLOD.esp.
