ok so i was playing this casually and then i went to undo one of my moves, so i pressed the undo button, and for some odd reason, the game started duplicating kings and rooks every time i undo'ed. Also the rooks were moving in odd ways that normally wouldn't be allowed. I didnt know where to post this so I decided to do it here. I couldnt find anyone else that had the same issue and sorry for bad quality and no audio i was on my school computer
