It's after you've pressed the button the first time. You get to the actual screen where you can click to give 10 Food to gain new followers. But after you've done that it feels like it should say either something like 'There're no more people for you to recruit', or just have you go back to the camp screen, because atm it shows the same text as you get with the first time you recruit but you can't click the button anymore.
Can't check it now since I'm at work but it wasn't possible for me to attack Obstacles other then with my Followers. Had to waste a few attack turns for some loot.
I'll start keeping track of the typos again. Only wrote down one so far but seen several more. One I wrote down yesterday:
3 momentum Settler card with Rage description: 'If unit kills it's target in combat, refresh rage unit.' 'It's' should be 'its'
