Error: 0 is not found and glitched sprite

[Neeshka2]

Enemy sprite glitches when it moves using this movement script, also enemy seems to move diagonally with it:

$gameMap._events[this._eventId].moveStraight($gameMap._events[this._eventId].findDirectionTo( $gameVariables.value(59),$gameVariables.value(60) ));

Variables 59 and 60 are Player's X and Y coordinates.

Gives following error when enemy touches the player.
