@Crazy Cat Lad I was in the lead in my Vault Challenge game, now it has completely disappeared and I can't get it up on any of my browsers or Win10 game !!! This is a complete joke, why release these games and waste players time when they are full of glitches !!!
Please make sure that the app is updated and that the game is connected to your King or Facebook account. Force closing the app and restarting the device may also help.
