One thing I think is funny is in my notifications I will get a double period at the end of a notification for a chapter such as my last one. No such user liked Private Johnson Opens Fire Without Orders.. Any time I add a period into the answer the notifications for that chapter always add a second period but not such period is displayed on the chapters name so if I don't add the period it only has one on the notifications but none on the chapter page.
Notifications are meant to be complete sentences. E.g. [username] published the chapter [chapter title] in [story title]. or [username] liked your chapter [chapter title]. When the notifications get delivered, the placeholders get replaced by the real values. So if your chapter title has a period at the end, you get the period of the chapter title and and then comes the period of the complete sentence. In your recent activity it looks like RicoLouis published the chapter Private Johnson Opens Fire Without Orders. in "Picture Perfect". so you have an additional period in the middle of the sentence. The reason for all this is that it is assumed that a chapter option is a chapter title. And so it usually has no period. (Except for questions marks.)
