Seems there was no cross-post for the GoW blog to the forums for this one. I couldn’t find it from searching, either (only thanks to @icy in this thread: Queen of Wands missing in the Vault)
2-3 months after the Kingdom Pass ended, is what it says. Weirdly broad time frame, tbh.
Also a disparagingly long time – I wasn’t a fan when Kingdom Pass introduced a new standard of delay for releasing its paid event content, from the previous typical 3-4 weeks… 
and I guess even worse when they forgot to add things so that it was longer.
Kingdom Pass ran for two weeks from 1 Jan, so we’re looking at ~ 11 March – 8 April.
