My gf's phone fell to the ground and changed the date to the year 2000, then fallout shelter began to act weird, giving power, food and water rooms longer times to give resources (24 hours) and changing the risk of express mode to over 1500%, another thing is that explorers were exploring in negative and they came instantly with no caps, guns or armor.

Now, 24 hours later, rooms are still demanding 24 hours to give resources and explorers keep exploring the wastes with no purpose, they do absolutely nothing.

What can be done, is the vault totally lost?
