I Do Not Have Permission To View My Own Content?

[Denim&Venöm 16,509]

So I'm searching for the past threads related to Poniverse's secret santa event last year. I find a thread from the person I gave to. I click, but then get an error message saying I did not have permission to view that topic. Fair enough, it's somepony else's topic. 

But then I find my own topic on the event, and when I click that, I get this same error message as the last: 

 

Sorry, there is a problem

You do not have permission to view this content.

Error code: 2F173/K

 

So why am I being locked out of my own thread as well as those of others?

The Secret Santa stuff got moved to an Archive that is staff-only accessible, but I can't remember exactly why.

All the MCM 2014 threads appear to be buried in the Castle Throne Room: 

 

I used searched on the tag Making Christmas Merrier, and they showed up on the last page.
