From the News:

"We have updated the Questing System to remember your recently completed/skipped quests so it will not immediately give you the same quest again. However, please keep in mind that these quests are assigned randomly, so you may see some pop up that you completed a day or two ago."

Well, I just completed Flirt, and the quest that replaced it was -- Flirt.

In addition, the dropdown when I completed it said I received 100 EBs instead of the 2500 EBs and 500 Store Credits I should have received, according to the Quest Hub.
