Have just looked at the database. The replies/comments that aren’t appearing are of component ‘activity’ rather than ‘groups’. Could that be the problem?
I have the same problem. I can see the entire thread when I go to http://growthedge.net/members/simon-d-orsogna/activity/143/ but there are lots of replies missing from the main activity stream, and there are replies missing from http://growthedge.net/members/simon-d-orsogna/activity.
This is a members-only site, so you won’t be able to see the problem, but I’ll do what I can to help debugging, this is really irritating my clients.
I’m not using BP Labs.
