This is maybe the second time this has happened to me. It’s not a huge problem but it’s weird. I just posted to a thread. It was post #8, which would make it the 7th reply. The previous poster was Jettboy. On the forum page it lists him as the last poster, with the 6th reply. It’s as if I never posted. But when I open up the thread, my post is right there.
I do believe the system doesn’t update after every posting – it updates in batches – so there may be a bit of a lag before the system catches up with itself and listings are shown appropriately.
It’s the same reason post counts don’t accrete as people think they should – sometimes there’s a bit of a lag there as well. But eventually everything gets sorted out and things show as they should – but it doesn’t happen instantly.
