Hmm, nothing installed that affects the Gildergreen, other than Gildergreen Regrown itself. And the LODs are working fine for the 75% scaled version from quest stage 10, which also uses the fully regrown model. But nothing changes when GGR finishes on stage 15, it keeps the 75% scaling on the LOD.
Load order for my SSEEdit is currently:
USSEP
DynoDOLOD.esm
Gildergreen Regrown.esp
DynoDOLOD.esp
I mean, I am seeing 2 different references in DynDOLOD.esp for the tree. But they're both scaled to 0.75, maybe one of those shouldn't be?
gildergreenregrownesp_0012DE_Tamriel_DynDOLOD_LOD
gildergreenregrownesp_0048E8_Tamriel_DynDOLOD_LOD
Also, the tree reverts to the base version (RefID 000461ce) from Skyrim.esm when GGR finishes on stage 15. So it leaves no trace of itself when it's done. Maybe that's causing an issue?
And I'm generating 2.x LODs now will report back tomorrow (3am here)
