This was happening to me as well. Turned out I needed to rebuild my smashed patch. Try rebuilding any bashed/smash/skyproc patches you have before running DynDOLOD. I have another problem though. With DynDOLOD active in my load order I have a consistent and repeatable crash when approaching the college of winterhold (with Immersive College of Winterhold installed). Right when I pass the general store in Winterhold towards the entrance where Faralda greets you. If I disable DynDOLOD.esp I have no CTD. Disabling the plugin via the MCM doesn't seem to be enough. Any ideas on this one?
