So I was playing with myself, and this happened: I was with my white king checkmated with tower at C4 and another tower at D6, both black. White king at D1 along with white bishop at D2. A black queen positioned at F1. I was confused why it did not check mate... I went for the kill and The queen teleported to D6. After I could not move any piece. This happened in Plain Chess. Why did it happen?
