I've had kp even with rest mode on 5.05.
Yeah true I have had it happen when trying to wake from rest mode. It's not perfect you're right, but overall I don't think it's that bad. If I get a kp I just restart it and do the exploit again, then use rest mode and probably don't have to do the exploit again for months. I would get very annoyed without rest mode though. Poor 7.02 people.
