Thanks for reaching out. Do you by any chance still have the previous RoonServer Logs folder, from when the corruption occurred? If you can upload it to the below link and let us know once uploaded, we can take a look to see if there are any clues to the corruption type.
@noris Thanks for the quick reply; I have uploaded the logfiles both from before the rename and after. Note though that the symptoms shown in the screenshots are with the newly restored database/data folder anyways.
