Inventory Slot and Delivery Pod Bugs.
When we Ress our teammate who died while performing the Advanced Order: Stockpile quest, if that person has a Patcher II Module or Backpack and the Inventory slots are full, all the Items occupying those slots are destroyed. In addition, if the game gives a Fatal Error when we do not complete the Items we put in the Delivery Pods while doing this task, all the Items in the Pods are destroyed.
