I've replicated this. Looks like it's not being saved in the player's attributes (not shown in "/open account", even after reconnecting).

Testing code:

PHP Code:

function onCreated() {
  temp.pl = findPlayer("YOUR_ACCOUNT");
  
  temp.pl.clientr.test = {{"one", "two"}};
  temp.pl.clientr.test[0][1] = "three";
  
  echo("server: " @ temp.pl.clientr.test);
  
  temp.pl.addWeapon(this.name);
  temp.pl.triggerClient("gui", this.name, "check");
}

function onActionServerSide(temp.cmd, temp.data) {
  if (temp.cmd == "returnCheck") {
    echo("client: " @ temp.data);
  }
}

//#CLIENTSIDE
function onActionClientSide(temp.cmd) {
  if (temp.cmd == "check") {
    triggerServer("gui", this.name, "returnCheck", player.clientr.test);
  }
} 


Output on Ol' West:
