I know lots of people have this problem. I have had this problem since 2017. still seeing it. Basically every single building I click on has only 0-3 people working at once. I have no water, because no one is working, and food is falling. Honestly I dont know how the colony is still going with literally maybe 100 people of 27000 working. I'll answer an questions possible while trying to figure out this problem. In the past, ive found that... killing...the whole population works... i dont wanna have to do that this time though.
