When I first started, I got ZERO quest items from the first Earth event I did, when I needed all of them.
2nd event I got a Device Gear and Device Antenna, no power cell.
3rd event, I got Device Amplifier, nothing else, and no power cell.
4th event I did, I got ZERO items again, and I need Damaged Transmitter and Device Motor and still 10 Power Cells. But I got ZERO items!
