There was some confusion in this. It's not a bug that it doesn't take you to the unread post in the next topic.
Right, that's why I clarified which part was actually, truly a bug. I would of course vote for it to act the same way as if I'd clicked on the topic. I can't find a sensible reason for it to behave in a different manner. I'd be interested in hearing why someone would want it to behave differently than when directly selecting the topic.
It is a bug that it doesn't always actually take you to the next topic, but sometimes will take you to the actual first topic in the forum even if that's not the next topic.
No arguments here I think. Plus the additional oddity of 'Index' returning to the previous topics page.
