I am not aware of any such issues. But without story URLs that exhibit the problem, an error message, a debug log showing the issue (or ideally all of those), there's nothing for me to investigate.

Sorry about that - I forgot to attach my log files from one of my attempts. Have attached it this time. One of the stories that I know that has updated is https://archiveofourown.org/works/2812049 and I have attached the exported ePub from my library as well. I tried reverting back to Calibre 3.48 as a test to no effect. Do you have the version of the plugin from around the beginning of October so I can revert back to that version as a test?
