I typed drone fuel, Drone fuel, and Drone-fuel in the setting changing the fuel type from petroleum-gas. Nothing worked, The name changed, but the icon stayed as petro gas. The Drone delivered the fuel, but it instantly disappears. Suggestion? Thanks.
Posting for anyone else who finds this by google like I did. In the mod settings under Startup change the Transport Drone fuel from petroleum-gas to drone-fuel. When loading your save make sure to click load save and not sync mods.
