Posts disappear and then reappearing?

A weird one, but still. I was searching for something else and an old thread from PH came up on google.

But I remembered replying to that thread. But the other replies on that thread disappeared, so it now looks like oldmanbm was talking to himself.

Snip below how the thread loaded.

It's just a bit weird.

Edit - I searched though my post history, found my replies while I was writing this post, and they then reappeared.

Yeah probably this!

Being logged in/out doesn’t affect that button, probably just the page loaded with it ‘clicked’
