v.70 hiring another person results in this

[Hawkido]

the only person in the roster is the new guy... my other guys can only be selected on the map... saving and reloading does not fix this... even using reset squad positions doesn't help.

I have the same problem except in my case it wasnt cause by hiring anyone...just importing my squad caused this so i have my old squad plus a squad of clones. I dont remember researching and building a cloning vat either

happend to me once, but couldnt reproduce it so far.
if its the same problem i had then the game made a new platoon for your new guy,
you can check that by looking in the kenshi game folder under save and then the name of the save folder and there under platoon there you look for Nameless_1.platoon if there is one with another number then there is probaly so far no way to fix it so i would start a new game,

Sounds like a growing pain as they get ready to roll out a "multiple squad groups" UI update.
