I've noticed that since the weekend a number of thread groupings seem to have disappeared, including the General sub-heading under the General heading. The posts are still there as you can access them from the red block on the right, which then does show the sub-grouping but it disappears if you go back up the breadcrumb trail.

Is it just me or have other people noticed the same design feature? 

No it's not just you - I'd noticed the same

Yes it has gone. 

The forum now seems to have lost several categories.

Yes, I thought several others had gone too, but couldn't remember which ones.

I'm glad its not just me that is not not-seeing things (so to speak).

I noticed it too 

I blame The Donald. Tariffed them out of existence.

I will get the tech chappie to have look at this.  We can't have sections of the forum taking unauthorised leave of absence...

It seems that the missing threads are starting to report for duty. Have they provided any excuse for going AWOL?
