I usually rerun DynDOLOD every time (generating from scratch), but this time I just wanted to update a single mod that was causing errors in DynDOLOD's log, and so I tried using DynDOLOD in "update plugins" mode. It was much quicker, but it ended with a huge error message in a popup:
[Window Title]

[Main Instruction]
One or more errors occurred
