Xbox one X - Dayz 1.18.154955.

If a container (barrel, tent, car, clothes or on the floor itself) has enough items to have more than 1 line of items, when opening the inventory only the first line is shown.

Example: a barrel with 150 boxes of 5.56 ammo, when opening your inventory near the barrel it will only show the first line, not the entire contents of the barrel. (when opening 2 ~ 4 times it will eventually show all the contents)
