Posts disappeared then reappeared in wrong order after my reply

[dx]

Something very strange happened just now. I was replying to a thread whose last post was at 09:56 AM. I replied to it almost as soon as it appeared, but the time of my post was shown 10:34 AM and suddenly 4 posts appeared before mine that were not there before!

You mean the time stamp of the posts preceding yours was later than your reply?

No the time stamps were in the right order. It's just that the last post I saw (just approximately a minute before I replied) was the 09:56 AM one.

I had this problem as well with some of my school's computers. I never had this problem with my personal laptop. I think for some reason the browser is loading from cache instead of refreshing from the server.

Turns out you're right Defennder:
