Bangkok Boss Glitch

Perhaps lots of you know this issue. I know this glitch is an old news. Zynga had fixed it. But some of lucky player still can do this. Simply click "Claim your bonus" on your friend posting. After the MW page load perfect, all you need is refresh the page. Do it with F5 or Ctrl+F5. If you are lucky player, you will got "You received x experience points and B$1,000 for helping xxxxxxxxx". Otherwise, you will got nothing :)

Check the screenshot:






Again.. Only works on lucky player. I can't do this glitch, how ironic...
