Blackwidow V4 Pro column of key stopped working.

For some reason when I had my keyboard plugged into my work computer overnight, I woke up to find that three columns of keys were not working.

I unplugged the keyboard each time and plugged it back in, and then it worked again. Is this something to be concerned about?
