Dark Mode (BETA):

After looking through the guide you’ve linked I’m not entirely sure what the problem is. Have you followed the step where you bring up the browser and enter your ticket number? If the 10,000 W is definitely showing up in your Daum account then it should also be showing up in-game and I’m not actually sure what the problem could be. Have you tried restarting the game since? If not this is probably it. If you have then it might just take a while to go through.
