how does somebody clear one's void? do you go to a town with 10 villagers or somethin.
You go to a town that has 10 villagers. Your villager will try to move into it from the void and won't be able to. Towns that have had that villager before but haven't gone through the 16 villager cycle or which have a permanent set of 10 villagers are ideal.
... That's the theory, at least. I've also read several posts recently claiming you can't really clear your void, and others that the chances of that villager trying to move to a town with a free spot get lower each time you visit a full town. I don't think we know for sure but it's probably safest to assume you can't.
