Probably an error.

You were actually winning and this should not have been a draw by repetition.

Ok thanks I could not see the repetition and I thought I was going crazy

You had the same position on the board after moves 31, 33 and 35.

When the game ends by a draw, it tells you why.
people are pointing out a repetition, do you either misread it or it was a bug
