In <a href="http://buddypress.trac.wordpress.org/changeset/13344">[13344]</a> we made sure to avoid the last entry(ies) of the stream to be duplicated if some other members published other entry(ies) just before a user clicked on the "Load More" link.
2 mistakes were made while generating the `BP_Activity_Activity` MySQL query clause as well as the Load More link query variable causing a regression as some activity entries were wrongly skipped from display each time a user was clicking on this link.
1. The MySQL query clause built in `BP_Activity_Activity::get_filter_sql()` needs to also include the last inserted Activity ID using the `<=` operator instead of the `<` one.
2. The query variable added to the Load More link needs to remain the last inserted Activity ID at the time the stream is first displayed.
