Board gets stuck between two moves

[ajaydheeraj]

Sometimes when quickly holding right arrow to progress through a game, GoKiBitz will get stuck between two moves where I am unable to move forward or backward at some move number: clicking forward will show the current move and then the next move, while clicking backward will show the current move and the previous move. Only way I've been able to solve this issue is to just reload the page or wait for 15-20 seconds and then move forward, Safari on Mac OS
