There is a problem with the inventory configuration, there is a conflict when you equip or pick up any item from anywhere “Chest” “Bench” “NPC” @Community
To alleviate this and not waste too much time, you should switch the option to “Disordered” both in the chest and in the inventory, this will reduce time and solve a large part of the problem when equipping any equipment or armor… I hope FUNCOM resolves this quickly
