This was happening to me and I was searching it up and found this forum. I was playing pretty bad at first, like thinking I could sac my bishop to grab his unprotected bishop after delivering a check with my knight (move #7), but at move #16, me as white, it made me grab the knight, which I knew was protected. My opponent, @pgc93b, has a very hacker-like user.

What do you mean by "hacker-like"?
Talk to support? idk. Could also be something with your device.
