Stop QQing lol. The thing where the cooldown freezes is a game issue, possibly due to increasing speed on bot.
Here are two versions, download and hopefully works well for you
If you have problems with card clicking
ONLY Download this one:
If you have problems with the cooldown
freezing Try this one:
For the card clicking I can guarantee it fixes it. For the cooldown, not so much since it's game related. I think the issue with the cooldown is due to the speed increase on the bot, so the speed is reverted back to default and hope you have no issues
