I had an invisible knight
I had 3 knights, lvl 1-1-2, I intriged opponents knight away from my way, and later tried to make another new one on that spot. The only thing I could was to activate “my” invisible knight, which it wouldn’t allow me to anyway, and I couldn’t see any knight. Then I tried to upgrade one of my lvl 1 knights, but couldn’t. First time I restarted there was no knight visible, but it appeared when I later restarted it again, and it was “my” lvl 2 knight. I didn’t make it, or at least couldn’t see I made it. I restarted the game three times with the result that I got kicked out of the game, because my turns took too long. I was winning.....
