I ended up being pointed that direction already, very interesting stuff. Does DynDOLOD generate strings on the fly? I ask because I use a completely static load order, have used the same mods for 100+ hours across five saves. I've only experienced this issue on one of them, my longest, and only after I started running through the landscape at extremely high (VL base speed + 60%) speeds. It's definitely the issue mentioned there, all of the symptoms are the same, I'm just curious as to how this arose in the middle of a save. Side note: A large number of the generated script instances were unattached. Is this intended? Edit: I figured out the answer to my primary question by looking through your previous posts. It does, and the new beta scripts you uploaded address that. I didn't come here expecting a fix, but you've provided one before I even arrived, awesome work!
