We're aware that some or all of the Weapon Caches, as part of a quest, are currently unfilled. We are working on automating this process as currently the caches are manually filled by a member of the team in order to provide custom and hand-selected items. We are going to work on developing tools to automate this while retaining the level of customization that doing it by hand provides. Keep an eye on these chests, we will also update this post when we have more news about this for you. Thanks for your patience!
