by "tried to pack output myself and load it into the game" I mean that DynDOLOD didn't suggest to zip output and exit after the last error, so I tried to zip it myself
I have the exact same issue but have no idea what mods touch riften in any way (dyndolod worked fine before and I don't remember installing mods that affect riften after it)
Also, I've tried to pack output myself and load it into the game, but there happend a bug with light source causing high density particles near them
