Constant rebooting after slight changes to uEnv.txt

Hello,

I made some slight changes to the uEnv.txt. Majorly, I wanted to remove the console=-line.
After that, my RockPI S is now in a reboot-loop. I since then reverted those changes, but the RockPI still is constantly rebooting now. Why?

It happened again.

It seems changes in the uEnv.txt are only tolerated once after the system has been set up. After that, changing the uEnv.txt are causing the system to not boot up properly anymore. The only thing left to do is to secure the content of the home-folder, reformat the SD-card and begin anew. Very frustrating! Where can I file this as a bug?
