MU Online adds a new item on the Goblin Point shop, called “Unique Accessory Box”. This “fizzy” box contains various accessories, so if you wanna buy it, please have in mind that the number and kinds of options are perfectly random. Also, last week Windows 10 was released and it end up on many gaming computers. That’s why, the MU Online team is receiving reports of gameguard error occurring after Windows 10 update.
One strong and simple advice comes from the MU support team and sounds like : “We suggest all Mutizens against updating Windows 10, until this issue is resolved completely and official notice is announced”. If you are still in the Win 7, 8 or 8.1 era, then stay cool and play!
