I've got a save where the drone is not re-callable, it's been four nights since I first called the drone to sell some stuff and the button has since stopped working. I checked the radio tower as well as the console command, both appear online/fine. It's a regular story mode save. The first box the drone ate was the luggage bag you start with, not sure if that's part of the bug or not. I can provide the save file if you'd like.
All of my saves are bugged, none of the drones work. Re-downloading the game and clearing the %appdata%/local/votv didn't work.
