Any specific inventory container (pants, shirt, car, tent, etc.) that has more items in it than what the inventory screen as a whole can display at one time is extremely hard, or even impossible a times, to navigate. To elaborate, the best example is a car or tent that is full or nearly filled. This is not an issue with the capacity limit of the container but with the actual number of items in it. In other words, if I had 4 items that took 100 slots stored within the car (capacity of 400), there would be no issue, as all of those items would be shown in only one line in the menu. But if I have 100 items that take 4 slots, you will need to scroll to see all the items, which is where the issue lies. When there are so many items in that container that all of the contents cannot be displayed within the inventory window without the need for scrolling, the inventory menu starts jumping erratically, and it's almost impossible to know what item is selected without waiting for the item description to pop up. Even with the pop-up description, you can't know what items are adjacent to your current selection, thus you can't reliably retrieve the item you actually want.
To further explain, this is not an issue of scrolling through different containers, such as your shirt, pants, backpack, and so on. Scrolling through multiple containers is not an issue. But when a SINGLE container has so many items that the entirety of inventory menu cannot display all items within that container, this issue starts to occur.
Sorry for the redundancy, but I'm trying make clear what the issue is as it is very specific but also incredibly game breaking in these cases. It makes navigating through a very full tent or car infuriating and has even caused me and my friends to lose valuable items. It seems to prevent moving items to and from a container that has this problem which leads to even more issues. Please fix this soon because it is preventing our progression in the game, leaving us little more to do. We can't properly store things we find, and so we are beginning to lose interest in the game because of this.
