When the warning occurred, I didn't think the reason was my party. I didn't even think to look at my party because my friend had been gone for nearly three hours. I realize that it could have been prevented, but the message could have been clearer. I don't think it's fair for me to be held at fault in this situation and I think there's room for improvement here. The message could have been "One of your party members failed to accept the ready check" or something to make me think to even look at my party list.
