Please, provide a clear description what the bug is: Chromie after doing a quest line would let you buy Chronoboons at Tanaris instead of WPL. IDs of affected creatures, items, quests or spells with a link to the relevant page:
NPC: https://database.turtle-wow.org/?npc=10667
Expected behavior. Describe how it should work: She should be selling Chronoboons in Tanaris. This glitch makes playing Horde even crappier than it already is.
This is not a bug. The crystal was supposed to summon Kheyna Spinpistol not Chromie.
The crystal will summon a different NPC depending on the quest you're on. "Return to Kheyna" will trigger Chromie spawn, it's part of the story: Chromie will appear instead of Kneyna to explain to you your wrong-doings.
Still not explained why she isn't selling the Chronoboon anymore tho ifi ts Chromie still.
It's a different instance of this creature. We don't want that players can hand in quests unrelated to this specific story. This crystal isn't supposed to summon her at all if you're no longer on the quest, this' is gonna be fixed as well soon.
So Horde players gonna have it more annoying yet again for Chronoboons then.
