BIS_fnc_KK, I should have been more clear in my initial post. The items get removed, but the vehicle cargo space is not freed up. See this image: http://i.imgur.com/JzXbA9g.jpg

Note: This only happens with vehicles that spawn with parachutes in their inventory.

Have you tried aligning your control right by setting the style to 1?

Ex.
style = 1; //Align right

You should've done research before you purchased the game. You can't blame a company because you didn't look into something before you bought it. It's not their fault your computer isn't up to date.

Looks like the latest update fixed it.

I've rar'd and uploaded the DirectX folder.

Let me know if you need anything else.

Edit: Also, i've already tried verifying my game integrity/reinstalling team/reinstalling arma3 and it's not my graphics card, all of my other games are working fine.

Here is the folder C:\Users\<Name>\AppData\Local\Arma 3\ rar'd.
