I try to always find another person to take them when I'm moving out a villager, and sometimes TT to keep it on the same day so I can do so. For some reason the idea of them just being voided bothers me.
oh, same! I hate when my villagers get voided, even if they're ones I'm less fond of. That's actually why I'm trying to give Bree away right now - she finally pinged to move out last night, and I'd like to rehome her ASAP.
I'm terrible, because I hadn't even pondered it before. Seriously, my void is swimming in villagers that I threw out there for cycling or plot resetting or just because... I mean, I must have populated the void a hundred times more than my own village...
