Ah ok, thanks for the detail - I'll look into it.

@WatcherOfTheNight that is a bit strange, I've not seen duplicate bookmarks before.

How often do you see the double posts? Do they clear when you leave the thread and reopen it again?

We added a fix so that it's very difficult to post twice (when you get the 'post failed' alert), but it could be that a single post is being shown multiple times by the app.
