my game was taken over by somthing moving my moves

There has been a similar exploit way back in the day, probably 2012 or 2013. IIRC the URLs for spectating and playing were different. One of the guys I knew gave me his URL instead of giving me spectator link. Sure enough I was on the same page has him, logged into his account and both could make moves. I even stayed logged in after the game was done and could play games from his acc without knowing the password.

Perhaps this is a related issue? I can hardly imagine some random hacker targeting you specifically.

maybe there cold be made a defence system that made it inpossible to have dual conectjon to make moves? i ofcours do not think it was my oponent doing it sorry for him to

Maybe it was aliens.
