Fetching Leapfrogger's Upgraded Card 404s

Leapfrogger’s card data points to an upgradeId (74974) that does not exist. Steps to reproduce:

  1. Fetch: Leapfrogger by ID (72042).
  2. Pull the upgradeId from the battlegrounds member: 74974
  3. Fetch again by ID.

Sorry, I can’t include the actual endpoints I’m hitting because I’m apparently not allowed to include non-blizzard links.

You can also see it affecting the official minion search, which shows nothing for the Triple Card: https://playhearthstone.com/en-us/battlegrounds/72042-leapfrogger
