One of my friend , had a 7 days value pack for his account on Black Desert EU Servers. He knew his value pack was going to end so he made it so he had 16 slots left with nothing in it to make sure he loses nothing from his inventory in these 16 slots that the value pack gave him. When he got back on after his value pack was gone, Five Items that he made sure they weren't in the 16 slots before he loses his value pack, got stuck in the locked section of the inventory. He tried lot of stuff like logging off then get back on the servers to see if it was just a bug but it was still in the locked section of the inventory. These Items are : Agerian Helmet +14 Agerian Gloves +12 Agerian Shoes +12 and two green pickaxes. It reflects on his character's progression and he doesn't want to start a new character just for that or even buy another value pack for a bug like this. Thank you for your understanding !
