Got the same issue here. Planned my whole new smelting area with Transport Drones, just to find out I couldn't move any product.
I can confirm that at least the worst case fix suggestion works: simply opening Transport Drones.zip and adding "(?)angelsindustries" to the dependencies in info.json made every plate appear in game. I also had to change manually fuel to 'gas-methane' (I'm using Angel+Bob+Py) in mod settings after this change, or the fuel depot would not work.
