I messed around with last build, only once so far but by day 5, my engineer was getting more and more behind on his maintening the power, took 2-3 days for custodian to move 51 units of food to another storage. I dont know if they are sleeping more or talking more but doesnt seem like much time gets invested into work.
Did like the rank pins but didnt play long enough to see NCO/Officer ranks.
