Previous version I was running over 896 Citizens.
With this version it started to collapse from lack of items sent and dropped from Level 4 to Level 2.
Now the main problem is there is lack of Oxygen and Survival Food.
There is just enough to keep the Colony at 537.
I added 4 more Oxygen and 4 more Food and did not make a difference.
Still staying at Level 2
Did notice that many Habitats are getting Oxygen every 63 seconds and Food every 27 seconds even when the item bar is full.
I have 64 Habitats in various levels with, 20 Atmosphere Processors, 20 Simple Farms.
The Consumption numbers are Oxygen 0.52/s, Food 0.52/s.
The Production numbers are Oxygen 1.25/s, Food 1.43/s.
