I really hate whenever I try to explain how some bad rules can be abused and immediatelly get someone say shit like "If this happens in your group, change it" as if that would solve the problem. And whenever it is not soemthing you witnessed personally, then it means it never happens and could never happen.
You may not be paying attention to me, but I thought you might want to pay attention to yourself. We absolutely CAN change rules at the table. It's called a house-rule. You keep pretending the issue is one that can't be improved with a rule change, but yes it fucking can.
Are you just going to "thoughts and prayers" approach that? Or are you going to post online about the exploit to mitigate damage while letting the company behind the game know about the potential exploit? I'm going to assume the first, since you said "nothing needs to be done" unless there's a person to kick from the table.
