And it happened yet again.  Nowhere near 200 moves, and had made a jump three moves before forcing a draw.  I can guarantee you that at least 50% of the time it happens when you’ve gone from 3 to 2 to 2 to 1.  It will always happen when chasing the last man up the board.  It happens often enough that if it is a bug it would be easy to find, however no one seems to want to address.
