computer level 8 on 2 piece handicap game played S45-56+

How exactly is this move illegal?
Silver can move diagonally in every direction.
because it promoted without going into the promotion zone.
My mistake.
This is actually not a legal move.
Move 56 of this game: lishogi.org/Uubbz12z#55
Looks like there are two Silvers that could move to the 56 square, and somehow the computer moved the wrong one. S47 to S56 and promote would have been legal.
Fixed, sorry about that.
