>the post that appears later always has the earlier time stamp
Looks like not always
From what I have observed it has to do with the vanwa verification. The verification expires in two cases:
a) After some time
b) when reset server-side
Posting will still go through, even with expired vanwa verification, but it will appear as if it hangs.
I believe that this is also connected to the images not showing up anymore: It seems as if the images-server (media.kun.top) has a verification-entry that expires two (or so) minutes earlier than the one here on the board.
With me, images always stop showing about 2 mins before I have to re-load the catalog in the other tab to get a new verification.
