This works probably 1 out of 3 times I attempt it.
One day whilst I was leveling a new character with a friend, we had just completed a daily quest, i leveled from it and then windows bluescreened. I restart and get back in game and I have the same EXP as before the crash(aka I still had my extra skill point and wasn't deleveled) but I can do the daily quest again.
What you do is find a daily quest that is easy for you to do quickly, make up a script that kills the archeage process (or just use the reset button on your computer) and when you complete the quest make archeage crash, kill the process, or quick restart your computer. If you're lucky you'll get the reward and be able to do the quest again.
