vBulletin 4 Request - Show previous/next links if you change default thread sorting

[final kaoss]

So, I've encountered an interesting bug and identified the problem. I'd like to request a mod that allows for the previous/next links to continue to work if you set the thread sorting to something other than default. In my case, alphabetically.

For various forums we have set the sorting to "thread title" (using the admin panel) to make sure they are listed alphabetically.

As a result we have no "? Previous Thread | Next Thread ? " links at the bottom of the threads in these forums.

Is this an imperfection , something wrong with our install , or is there a good reason for this ?

The code the looks for the next/previous threads looks based on the date/time the thread was posted and only that, so it must be disabled when anything except the default sort is chosen.

So to jump into more detail about the issue, I made this thread with live examples.

I noticed that if I visit a thread that is a couple of subforums deep, the navlinks dont show up properly. Example:
https://www.vgcheat.com/forum/playst...aystation.html

And here's how nested it is

Forum > Sony Chat & Cheat codes > Playstation 1 Chat > Playstation Cheat Codes > Thread Title

What I'm referring to by navbar_link is the next & previous thread navbar_link that show up below the thread replies. If you go *up* a subforum and view a thread, they show up fine...

So to give a clearer example:

Category > Forum > Navtags work in threads in this forum (Live Example)
Category > Forum > Subforum > Navtags do not work in threads in this subforum, because they are being sorted alphabetically (Live Example)

What can I change to rectify this issue?
