Hi MNHQ
Active says that it should show the discussions that have been most recently posted on, but I've noticed that it misses out chunks of threads (see photos) and when I hit refresh, it skips threads for the same chunk of time, but now slightly later - the two screenshots were taken about two minutes apart. Third screenshot shows a much longer time jump.
I think it's related to hitting 'load next'. When I hit 'load next' for the first time, there's a minimum 5 minute jump. If I hit refresh a minute later, that 5 minute jump is still there, but now affecting threads whose last post was a minute later.
