I'd love to be able to include some random civilians wandering around my battlefields (or maybe even an objective for some sort of 'rescue the hostages' scenario). Does anyone make anything compatible?

Hostage rescue/prisoner swap is a new objective coming up in the 2nd supply expansion FYI.

But, for now, check out skull forge studios. They even have the ice cream maker guy.
