Bug/Issue Switch Bugged Request from Wizard

Hi, just reporting an issue with a quest I received from the town notice board. I received a request issued by the Wizard, asking for me to slay 0 Dust Sprites, to receive a reward of 0 gold. I was able to hand this in immediately, the quest was removed from my journal without needing me to claim anything, and it may or may not have still given me the relationship boost for finishing a request.
Not a big problem but it seems like unintended behavior.

Thanks! - Calacene
