[Forum] Deleted Sub-forum is gone but stills shows in the admin cp

[DecNetPHase4]

I deleted a sub-forum within the admin cp.

But...

the sub-forum is still visible in the admin cp, but when the link for the sub forum is clicked, the error below is shown.

Invalid Forum Specified

On the main forum, the sub-forum that was deleted is still visible, and can be posted in and new threads started.

Is their an update counters or some other way to sink what the admin cp is seeing and what actually exist?

Thanks!

Was memcache, just takes a while for it to catch up...

Sorry for the dumb question...
