For the sake of aestheticism, I'd like to point out a terrible trio of visual spoilers :) They may seem petty - but Arma3 is so close to being visually perfect!
- The weird texture on the desk object (Land_TableDesk_F). Look at the surface of the desk and the drawers - it doesn't look right at all! It's almost as if the wrong texture has been applied to the model.
- The horrible smudge on the small bunker (Land_BagBunker_Small_F). It's the corner, top sandbag - you'll see it if you properly inspect the object in question.
- The sky-blue, weird, hole in texture thing. Enter the passenger seat of an offroad with an MX rifle and the RCO scope equipped. Look at the scope - it's got a weird, sky-blue hole in it. {F24990} {F24991}
