Pvz Heroes: Admiral bean Pvp mode bug

There's a lot of players using this bug. They have more than 4 admiral beans in their deck, which deals 2 damage to hero when the bean is played. On the third day, having only 3 suns, they can have 5 admiral beans on the playground. And even if the luck is on your side and you block that damage - they can have 9 admiral beans on 4th day 💀

I see players using this bug more than 4 years and I wonder why developers not doing anything, looks like they are not even playing their own game 😁
