I’ve noticed this, at least over the course of the past few days / week. The forum state appears ‘frozen in time’ when I haven’t logged in yet. It tends to ‘refresh’ only 2, 3, 4, times in a 24-hour period. The minute that I log in, I see all of the missing posts & comments that have been updated over the past several hours.
Odd. SpaceTime anomaly? Seriously, I imagine that unregistered forum users are not seeing the full contents of the forum at any given time. I understand that there were some server issues last night, but this doesn’t seem directly related. I’ve also had intermittent problems with uploads to the user file storage, but that one surfaces more randomly.
