Importing your Serializd diary could fail outright with a confusing error about an element of type Number. The cause was that Serializd diaries contain reviews of whole seasons and whole shows, not just individual episodes, and those entries carry no episode number. Jellyscribe tried to read one anyway and the whole import stopped there, so nothing was imported at all. Those entries are not episode watches, so they are now simply skipped and the rest of the diary imports normally. If your Serializd import has been failing, it should work on the next run with no changes needed at your end.
