Updating doesn't remove your saves. If you're on Android, make sure you're installing the update over the old one (don't uninstall.) If you're playing in browser, make sure you don't clear your cookies as the saves are stored as cookies
so how do you make sure you don’t clear your cookies? also, i just hit the refresh button on the page and everything went away
They don't clear automatically unless you set them up to do so. Programs like CCleaner can clear them though so be careful with your settings there
