I have some suggestions that might make the bank robbing thing more fun. First off, make it so it doesn't just say that "you must wait 30 minutes form the last bank robbery!" and add a countdown so people who weren't on for the bank robbery can know when they can rob it again. Ex. "You can rob the bank again in %time% minutes." Second, there are a ton of levers in the final room and i tried all of them and 2 work because one is right above the door and the other is connected with redstone probably. To fix this problem I think you should remove the ;ever right above the door because if you have to guess the lever its much more difficult to get in the vault.
