There's an issue that pops up from time to time, that occured only with two stories so far. One is finished by now, so it's a moot point, but the other is not doing what it should do.
FFF is set to "overwrite if newer" as well as "update from email". I received an update email today, and when I tried to download the story, it said the story wasn't newer. When I change the setting to "update", it works and fetches the new chapters.
The story link is:

I'm going to switch my settings to "update" instead of "overwrite" (especially because I don't remember why I set it to overwrite in the first place), so it's not an urgent issue.
But I thought I could share the work-around if someone else has the same issue.
