Not sure if this was a bug or intended. Issue as below:
Playing Naval RB. Cruiser USS Oregon City.
Start match. Press U, launch Scout Plane 1 of 2. Get plane killed.
Sail for a bit. Press Alt+U to deactivate the launch aim point for the second scout plane.
The problem: No amount of pressing U or Alt+U or clicking on the control bar on the bottom will re-activate the second scout plane so I can launch it.
Is this normal and expected or a bug or did I just do something wrong?
