We at Kemono Partychan are very sorry to hear that your Fanbox and Patreon did not update themselves magically! To remedy this situation, please follow the steps in order:
1) Make sure your Patreon and Fanbox account both have a session running
2) ONLY provide your session_id and FANBOXSESSID to the importer when importing, as explained in
https://kemono.cr/importer/tutorial - there is a field for you to put it
3) When running
https://kemono.cr/importer you should now have an import log and its progress in
https://kemono.cr/importer/status/[LOG_ID]; provide any part of the [LOG_ID] for debugging assistance.
Happy importing and thanks for sharing your Fanbox and Patreon with others, it is much appreciated!
