If you hadn't wified with anyone, then the first person ((or if it was a group, one of them)) you wifi'd with would have gotten the void.
UNLESS they had 10 villagers. Which should have "reset" your pool. Meaning, Gabi was sent off into nothingness never to return or appear.

I have a cycle town and I do a lot of trades with my main town... so... lots of practice. >.>
Someone voided Flora I think over a week in game days but never wifi'd with anyone. I was wanting to get a villager the next day ((they were picking up a villager from me)) so I made them go to my cycle town before visiting my town to pick up a villager.
Next day, Flora was in the Cycle town from their wifi void pool. XP

Another reason why I always wait until I have 10 villagers or someone adopts a villager from my cycle town before I do any trades between towns. XP
