I've built a leveled city plan. It simply WILL NOT upgrade. Level 1 is designed for 4 residents. As specified by @kinggath in the tutorial, Level 0 has only a few hand pumps and no generators other than the one powering the beacon. At this point, I've got four level 3 residential plots, 2 level 3 ag plots, a level 2 scrap lot, and a level 2 checkpoint... but the city is stuck at Level 0. Happiness is 71%. I gave in and added turrets and water pumps to resolve those deficits. Who knows why the power meter is full when there is only 3 power for all those plots that want it... Pulling my hair out here. The tutorial says to match resources for a given city level to the same plot level, but that fails utterly when the plots upgrade so far beyond the city. I just want to design a city that will level up on its own without micromanagement. Is there a minimum population per level? Is there some way to prevent plots from leveling up beyond the city level that provides the resources they need? Did I miss something in the tutorials? Argh! --specious EDIT: The HUD reads L0 100% and has for many in-game days. All Sim MCM settings are default, which seems the most expected scenario to support. EDIT 2: The cheat command successfully raises the city level.
