Is there a delay before getting your [Winter Bash](https://blog.stackoverflow.com/2012/12/welcome-to-winter-bash-2012/) hats once you meet the requirements to get them?

I accepted by clicking `I Love Hats` and logged in. Meanwhile, I meet the requirements for some hats, but I can't see them anywhere. (They are still grayed out in the Winter Bash page.)

It obviously started, because I can see users collecting them already (not just the December 16th 2012 one).

Let's take this present post as an example. It was posted 45 minutes ago, and I got an upvote. I meet the requirements for the `Constantipolitan Hat`. But I still don't have it. I should have earned a few other hats before posting this question, and I don't have them either.

Is it just a delay or a real problem?
