Wishful Willing challenge

Wish for Trinkets is not counting towards this challenge. Tried 3 times.
/bug done ingame.

Confirming: I just had this occur as well. Vastiri Desert, confirmed I had Trinkets selected (I clicked a different wish, then back to Trinkets to make sure it was selected), started the mirage but the challenge did not trigger -- no message on screen, challenge entry continued to show as unfulfilled.

I went into the mirage and completed it and killed all mobs, but that also had no effect.

Got a second occurrence in Tunnels. In my previoius try, Trinkets was the left-most option. This time, it was the center option, and not initially selected. I manually selected it, and opened the mirage, but the challenge was not activated. Similarly, completing the mirage did not trigger it either.
