The option "Stop bot when no more gold rewards and daily quests" doesn't work anymore. After the maximum amount of gold has been collected, the bot keeps playing games until it is stopped manually.
I have noticed this bug since hearthstone updated to v 3.0. With this patch, the in-game counter for games won until the 10 gold bag has been removed. This is likely to be the reason why the bot no longer understands when the daily gold cap has been reached.
The bug makes the bot unnecessarily play games for longer times, which increases the risk of your account getting banned.
