DroneDeploy not taking pictures

[John Deere Boy]

Dronedeploy worked great for me last year, but two out of four missions i've tried to fly this year failed to take pictures. The first time it took 19 pictures and quit (kept flying), the second time it never even tilted the camera down to take the first picture. Both times it flew the pattern just fine without giving me a warning. To fix the problem I landed, closed the program and restarted.
