In short after taking a flight that involved some video and a few photos I find that the DCIM folder on the sd card is actually empty. There was no error message of any kind and the files did not record on the internal memory. The cashe files recorded on the smart controller as normal. On the memory card there exist "support files" for the missing pictures and video with respective sequential file numbering. This is very odd but it's also a second time this has happened to me. Firs time I thought it was a fluke because it was my second flight with the bird and there where many updates science that time. Has anyone else come across this issue at all?
