Note: I am referring to the resource People, not Survivors or Heroes.
While putting Fortnite on the backburner for a little bit (to allow time for bug fixes, etc), I have made sure to continue checking daily to collect Research Points, grab my daily rewards, and send off Expeditions. However, after about a week of this, I've run out of People, which are required to send any expeditions past the first few that just bring back wood and stone.
I know that saving Survivors during missions grants 3 (possibly varies based on where you are in the game, but since I've started checking, it's always been 3) People per Survivor saved, but is there any other way to get People? I can do the Survivor missions solo if I have to, but it'd be nice if there was an alternative, since I tend to always find Survivors who ask me to find their medkits on the other side of the map.
