I've always had two or three specific forum sections 'stickied" so they stand out above everything else.

That seems to have gone away.

Is anyone else seeing this? is there something I can do to to get it back?

 

I think you may be referring to the Subscribed forums box that appears at the top of the page? If so, that's in the UserCP. It may have disappeared because there is a click to removing it that appears to be somewhat common for members to accidentally use.

All account-based options are in the UserCP:
https://www.f150forum.com/usercp.php

Edit Options:
https://www.f150forum.com/profile.php?do=editoptions

Show My Subscribed Forums on forum index page option approximately half way down the page.

 

Yes. Is your subscribed forum selection showing up at the top? Mine are subscribed, but not showing.

 

No, you have it disabled (hidden) in your UserCP. That's why it doesn't show:
