Idle farming scrap didn‘t work?

So I just bought the game and realized that all online features are not available including the scrap crew. To compensate I decided to leave the game on overnight. I have many camps and usually get 320 scrap from all of them. I read that you get the scrap every 20 minutes. I left the game on for 9 hours meaning I should‘ve gotten 8640 scrap but I woke up to a measly 1700. I was idling in jeet‘s fortress. What went wrong?
