I noticed a new bug that popped up. My time between captchas is 1:37:30 and on the count down timer it only says 37:30. It still mines for the full 1:37:30 but when the 37:30 timer counts down to 0, it just continuously reloads the page until it is time for the captcha to be entered again.
yeah i noticed that seems to be due to daylight savings time, so hope that means when its time to go back 1 hours we miner for 1 hour extra without catpcht lol
