a while later and without doing ANYTHING, MONA has returned to work on the auto switch, and I repeat I have not touched anything, nor restarted the computer nor the program nor the rig.

Sometimes this happens and I stop for a miner, I had to create a rule that if a miner is 2 minutes standing, start mining. But these random failures are very annoying. Thank goodness that the video is to show that I'm not crazy.
