When I open a map or create one in Scenario Editor, I get a wxWidgets error (issue #9307). The weird thing is, I don't get it when I first open Scenario Editor. Also, when I am about to place certain buildings (in the actual game), I get a "Program 'spirv/model_solid' with required defines not found" error (issue #9315)

Develop your city :
Cities can research upgrades that create economic activities around it.
Campaign the map with armies, interact with other armies or points of interest :
Get into battle missions by exploring ruins, or interacting with other player's buildings.
Below an attack on a encamped army. The map generate a camp fitting defending army size and composition :
