Not Bug Halloween Challenge

I completed the Halloween challenge before work and got 10 tokens, but did not receive a pumpkin box?
I noticed this twice on the same character.

 

If you read the event instructions from the Witchy Woman there should be no mention that the Halloween Challenge gives you a pumpkin box.

 

But it gives me a pumpkin box on other times that I do it?

 

There was a bug that we have fixed which made it give out Plump Pumpkin Boxes.

Please refer to the event NPC for the correct information on where you can find rewards.
