The order of the topics, unless you're sorting it with another criteria, seems to have gone wrong.  I'm assuming that the most recently updated topics are supposed to be at the top, starting with the most recent one, in descending order.

The one highlighted in blue was the last topic I started, right before posting this.  If you look at the dates, some of the topics are not in the right order.

The ones in black are sticky topics for that theme the ones in grey are normal topics

So that means that you are stickying topics for bugs that are not fixed yet?  That's nice.    Now I understand.
