Forum info not updated when approving threads
 

I got a couple of moderated forums.
When a thread is posted in there and I approve it, the forum information is not updated immediately, so after approval they won't show immediately as last posts on the forum home.
This does happen when I use the Rebuild Forum Information in the ACP under maintenance.

How can I fix it so that when a post/thread is approved, it will immediately show as last post on the forum home?

It's the latest vBulletin 3.8.7 PLx version.
