I suspect this happened when all familiar purchasers was done before looking under codex and identifying quests that is in the heroes journey.
Please fix this so the quests gets completed, or grant a free option to purchase another familiar from the assigned NPC that the quest is locked for.
The servers came back up and available to players at 03:00 (server time) on Thursday.
Everyone rushed to consume the new content, and took all three available familiars.
The issue is that Blizzard didn’t enable the new Hero’s Journey until 08:00 (server), i.e. five hours after people could have already bought all three of this week’s available familiars.
You currently have two choices…
- Wait until Monday’s reset, when more familiars will become available or…
- Complete the task in the Darkling Plane event for completing level 6 with 4 different familiars, as the reward for that task gives a familiar contract, enabling you to buy another familiar
