TOPIC: missing yesteryears?

It looks like some forum categories from older VTD adventures have been completely removed from the forums, instead of just being moved underneath Forums From Yesteryear. Is this intentional?

For example, my browser remembers that the V10 (Apr 23 2022) Bloody Nightmare thread was truedungeon.com/forum?view=topic&catid=679&id=254215 , but now that URL returns 403 Forbidden. That makes me sad, because if I ever decide to do another Bloody Nightmare run I won't be able to reuse the material I wrote for it before and will have to reconstruct everything from scratch (I didn't save it anywhere else because I figured the forum thread would stick around).

There are also some threads in an intermediate state where I can still get to them from direct links or from My Topics, but AFAICT it's no longer possible to reach them just by navigating within the forums. An example of this is truedungeon.com/forum?view=topic&catid=681&id=254340 (underneath V11 Adventuring Groups Form Here which is no longer displayed in the category tree)

I'm try to fix that tomorrow. Sorry.
