Yes. I've tried in the default mission - Comms menu, All cargo, select the contianer, red smoke emits from container take off, hover close by and hit the keybind i have for the External Cargo Indicator.. Nothing appears. (just for info, no problem with the controller indicator.. that appears bottom left). All i get is the voice commands left/forward etc.
And the same result if a load a mission that uses the CTLD menu. No green box.
