Sorry, Ill try to answer everything I think I understood.
whether Duplicati stopped looking
Files after stall
As far as I know, the only files that were modified in that folder were Kaiju and the Marvel savegames, they show in the Verbose log as Processed. Duplicati keeps going enumerating other files after processing them, so I assume it stalls during enumeration?
The entry I posted before is the last file to be enumerated, and according to the progress bar before, there were still files to be enumerated after that, somehow? This is also on the edge of my understanding and English ability, I dont know how else I can answer your question or how to interpret the data sent.
