New posts not showing on long running threads

Ridiculous I know but...
The Coronation Street thread from Telly Adicts keeps coming up in my active convos as having recent posts, but when I click on it the last post is from 12th Nov.

Its also happened in another thread a few weeks ago which I think was in telly adicts too.
I am on a PC using the desktop site.

Any ideas?

Have you tried clicking on page 2? MN now splits long threads into 500 posts as the first page.

HTH.

I thought I did, but I don't have to with other threads?
I'll have a go now.

Well how absolutely dull am I?

Sorry.
As you were.
