The problem I'm having recently is that the notification badge will show some randomly high number, like 53 or 108 or something, when there is really only 1 or 2. But it does clear when I read them.
I have the same problem with my other jeep forum apps as well, I wonder if it's a "Forum Runner" / host type issue.
I don't know who to ask / tell.
So far it looks like it's just on my iPad, my iPod touch looks ok.
