I can confirm the bug.
Using 20+ OrangePi Zero Plus with the extension board usb ports I noticed the same strange content of /boot/armbianEnv.txt as Magnet  described.
The file system seems to be fine, except this file. 
Since my systems use the USB from the extension board, once the port is not present, my device doesn't work.
My workaround is based on DoubleHP. I added a simple service that checks the content of the armbianEnv.txt file and react accordingly to the result. Her are the three files.
It works well on my systems, but please feel free to criticise it an point out any possible errors I made.
