The game obviously doesn't want you to have Portia if you lost her again omg
Hopefully if you do the 16 villager cycle you get her soon or if not hopefully you like your new Portia replacement..
Oh no I couldn't work with it if I lost a villager twice, they would just have to be gone permanently even if I loved them. Having done the 16 villager cycle for Genji not so long ago, I know how frustrating and time consuming it is. As difficult as it is, are you able to find somebody instead of her? sorry that happened
