Plus 44's description says, in order to earn it, you have to
Answer a question of score four or greater with an answer of score four or greater.
As far as I can tell, this answer should qualify me for this hat on Code Golf.SE (the question was posted ~3 hours after Winter Bash started). However, I currently don't have the hat.
Catija hypothesised that the hat can only be awarded if the answer is the first one (whether to reach 4 upvotes, or first to post, is unknown), which would fit with the fact that another user has this hat, as they had the first answer.
Is this a hidden part of the trigger, or is this a bug, and all answers should receive the hat?
