The new 'Daily Gear Giveaway' quest has (not suprisingly) a bug.
You can receive unlimited items from Gaga. Once you pressed 'Yes' to receive your item, press 'End chat'. The quest will appear again and you can get yourself another Cash item. The items usually vary between 30 and 50 charm EXP.
Go hire developers and fix bugs instead of sueing sites, Nexon... -__-.
