IPS Meta just got a round of Lifeboat badges awarded, 5 posts have earned someone a Lifeboat.
But not a single user has yet earned the Lifejacket badge, even though the criteria for getting that one seem lower than for getting the Lifeboat.
Usually, with badges that come in silver and gold, you get both for the same post, or progress for the silver badge also counts towards the gold badge (think Good/Great Answer or Epic/Legendary badges).
Is this the same for Lifejacket and Lifeboat, and is there just a little hiccup now because they're awarded for old posts? Or is there something in the criteria that makes it impossible to get both a Lifejacket and Lifeboat badge for the same post?
