IsRepeatedPosition can return false negative

[Amarcolina]

It seems based on my testing that IsRepeatedPosition() can return false negatives on the leaderboard, is this expected? it seems peeping at the source that the Board might be re-initialized before each move with a fresh FEN, and so loses the history of previous moves?

I made a bot called 'NoDrawsAllowed' which checks all available moves, and returns the first one that results in a board where IsDraw() returns false, else it returns a null move, and it was nevertheless able to end a game with repetition
