Copter executed old mission

Hi guys,

I came across an issue where the copter executed an old mission.

Steps:

  1. I connect to Cube using Telemetry radio and send new flight plan (25mph flight, etc).
  2. I clear flight plan map on Mission Planner.
  3. I read the flight plan from copter and verify it is correct.
  4. I start up the drone and confirm no issues but it was missing SD card.
  5. I insert SD card and confirm no issues.
  6. I fly mission but it flies old mission (similar WPs, 10mph flight).

Have you guys seen this behavior? Where does ArduCopter store mission data, same place as params or on SD card or both but prefers one?

Thanks
