I have a bugreport.txt from 2.52, if it helps. I ran into the "not being able to save or exit" problem if I used the advanced features (don't recall which ones) on high, but was able to complete the run with standard 'high' settings from the wizard. https://www.dropbox.com/s/dbvej1igcmpo0fs/bugreport.txt?dl=0 Two things I noted in the bug report. 1) exception message : Can not copy [REFR:0506312F] (places TreePineForest02 [TREE:00018A02] in GRUP Cell Persistent Children of [CELL:00037EE6] (in SolitudeWorld "Solitude" [WRLD:00037EDF]) at -18,25) from Unofficial Skyrim Special Edition Patch.esp into DynDOLOD.esp Assertion failure (C:\Delphi\projects\DynDOLOD\wbImplementation.pas, line 13521). 2) main thread ($560), inner exception level 1: >> EAssertionFailed, Assertion failure (C:\Delphi\projects\DynDOLOD\wbImplementation.pas, line 13521)00fdc7f7 +217 DynDOLODx64.exe wbImplementation 13523 +9 TwbGroupRecord.Create --> There is no "C:\Delphi" directory on my computer.
