Blizzard has shared an issue regarding the Corsage Pack. It seems that players who purchased it before 11:31 PDT have not received their Traders Tender. However, once those players make a purchase at the Trading Post, the Tender will reappear.

We want to make players who used the WoW Shop earlier today aware of an unexpected issue with the new Corsage Pack in the Shop. We deployed a hotfix for this at 11:31 PDT today.

Players who purchased the Corsage Pack before that time did not have their total Trader’s Tender amount update in-game, and will not see an update to their Trader’s Tender amount until they do a purchase at the Trading Post. After any Trading Post purchase, the additional Trader’s Tender should be displayed.

We apologize for any confusion this caused.
