My Snowdown Store is gone.

I'm not sure if it's something other than a bug, but my personal Snowdown store is no longer in my client. As in, it was there yesterday, and when I logged in today, it's no longer there.

I haven't been able to find any sources that say that this is what's supposed to happen D:

It was there yesterday, and I remember that it said it didn't end until 12/30.

Please + thanks for the help!
