o lord as long as colonists are NOT rendered distance to work does not matter .
All my colonys are set up like his and i stay t 98 - 100 rating .
what happens is a few get mad dont work less food mad a few more get mad and so on untill so many are mad food runs out .
the biggest thing to prevent this early in game is giving them money once you have this it is to late may as well shut off food let them die and start with new ones .
it gets really easy then .
His could be fixed but it would take so much time it is faster just o kill them off
