Offline Tower Defense: AI War

- Stalemate detection now fires twice as fast. It used to need about 50 seconds of fighting before it could trigger, and roughly half of the players who got stuck had already quit by then. It now starts judging at around 25 seconds, and calls the wave almost immediately if nothing has died while a crowd is still standing - so the fall-back-and-regroup choice reaches you while you still want to keep playing. - The offline vault now runs overnight: the cap went from 4 hours / 20,000 up to 8 hours / 45,000, so coming back the next morning is worth noticeably more than stepping away for an afternoon. - Three new optional rewarded-video boosts: gain one upgrade level when you are short on coins, double your coin and chip income for the next few waves, or double an offline vault claim. Every one of them is opt-in and nothing is ever forced on you. - The weapon shop no longer interrupts you with the store page when you cannot afford a row. - Fixed the daily bonus being claimable more than once in the same day.
