Since Update 1.11 it is not able for me and many other players to pick up loot from zombies with the "Square-key" directly into the inventory. Since the update you first have to hold the item of the zombie in your hands and then you can put it into the inventory. Thats pretty annoying..
Greets.
Try to put items of dead zombies directly into your inventory. Its not able because since the update you first have to put in your hands and then into the inventory.
Same for Xbox can not press x to move item from a dead zombie to inventory have to put in hand first, basically making you have to loot dead zombies without a weapon in hand. It's the same when looting dead players I believe too, and also can't pick up guns off dead players back, have to either have a open spot on back or cut player up. I will need to test more and report back with more or more accurate info.
