Disconneting your computer from the internet before you take chances lets you take back whatever you may lose.
HOW IT WORKS[]
Whenever you want to upgrade stars, sanctify a hero, or move to certain lab spots, disconnect your computer from the internet and wait a minute. Make the move you want. If it's successful, just reconnect to the internet. If it fails or takes moves or whatever, close your browser, wait a minute, and then reconnect. You will be where you were before you disconnected.
