What is this Bug?

I didn't even complete some of them!

What is going on?!

Have you ever given your account to somebody else?

Never!

I am the only one!

How is that possible, maybe someone changed your account somehow?

Nope. It was not even completed.

On your bio it says your brother used it. He could have done them

Maybe?

I'll ask him.

It’s your brother or you did them or some one else is on your account.

Nope!

It does not show it now.

??? That is so weird. Are you just tricking us?

NO!

ok. I belive you. sorry for asking.

Thanks.

Over the years, it adds up. It's hard to keep track. I've been solving puzzles for a couple of years every day, and all the sudden, I've done almost 4,000 puzzles on chess.com!
