Solved it. It’s down to a browser cookie called bp-activity-oldestpage. Flush that, and all is well with the world.

I’m not an experienced enough developer to know if this cookie has gotten set on me due to the work I’m doing on the site as an admin, or if this could happen to any random visitor. Can anyone advise? If that were the case, should this be reported as a bug?
