Log file creation condition?

I have one question.
Do I need special conditions for log file creation?
If the flight does not end, will not the log file be generated?
The reason I ask this question is because I lost my drones during the DD flight but I could not find them because no log files were created.
Please, who can tell? DD technicians would like to know if possible.

Hi @Sjho_77,

We’re sorry to hear you aren’t able to retrieve the flight logs from your recent mission. I’m sending a separate email with instructions to locally download your logs. Please feel free to follow-up with me via my email if you have any further questions or require additional assistance with this.
