Class playing Pirate Plunder errors out at certain level

My class is playing Pirate Plunder and every student got to a higher level - 11-13, and game would crash. The game would close and screen would show the Chrome “Aww Snap” error.
Any idea what is happening?

Hi Melissa,

do you still have problems using the activities? If yes, can you try to follow the steps on this page please? It seems that this is an error we can’t do anything about from our side.
