sometimes, i'll click on a topic and look at its list of Sessions, and notice the sessions are sorted in chronological order from earliest to latest. then after a while, the sort order suddenly reverses by itself so it shows the sessions from latest to earliest. it's not a blocker, but it's disconcerting when i'm trying to find a certain session and then suddenly everything shifts. i am not entirely sure what triggers the reversal, but i think it might happen automatically after i've been viewing the session list for a while. (in case it helps, this bug has existed for a while - it's not new with 2.7.0)
