Just to try to help provide a little more data and maybe zero in on what is going on?

I see the constant reloading somewhat frequently, especially with "new posts".
I casually mentioned it here in passing.
When pressing the go to last post button (
) shortly after a new post has been made (within 2 minutes?, 5 minutes? not sure - after a certain amount of time it won't let a reload loop happen anymore) the post will sometimes not appear or sometimes the page will be sent into a reload loop. Not sure what the cause is, but to me it seems like something might be out of sync or does not update right away and takes a few minutes to catch up (database?).
Go to last post button and Subscription links use the same #post123456 format on the URL. I'd imagine if you try a subscription email link
right after a new post has been made I think it would cause a reload loop just like the 'last post' button does for "new posts".
As Xyro mentioned before in post 15, removing the #post123456 stops the reload but disables the ability to jump to the newest post and most easily keep up to date on a thread.
Log in time 'lapsing' could be a factor. I don't save log in info/cookies to my browser. Log in lapses may cause some sort of disparity, but it may be a side issue.
