If a page looks stale after an update, a game will not load, or you just want a clean start, clear what Rehat keeps in this browser. Nothing on the server is touched; online rooms are unaffected.
Removes the offline copy and the service worker, then reloads from the server. Saved games, records and your name stay.
Also removes saved games, records vs computer, best times, your display name and the chat notice. This cannot be undone.
