When I go to Latest participated I get posts from a week ago. When I go to favourites Topics I get posts I participated in today.
I realize I can subscribe / favourite a topic without participating so there should be a difference in the two lists. The favourite list is showing both topics I have subscribed to and those I have actively participated in, which is correct behaviour. The latest all and latest unread are current, the last post under latest participated is from the 1st.
It is not a big deal to me because I can use favourites but thought you would like to know.
