Getting a message saying Failed to load mod "robotarmy 0.2.1" robotarmy/prototypes/bulding.lua:202: attempt to call global 'get_circuit_connector_sprites' (a nil value) Not sure what it means if someone could help me it would be much appreciated.
means you don't have Factorio v0.13.x, you must be on the old v0.12.x. Please opt-in to experimental builds (current version 0.13.15) for Robot Army to work.
