Whilst playing on either single-player or multi-player, a random thing appears on screen for a second then disappearing. It usually appears on the bottom of the screen. It happens randomly and very quickly, so getting a screenshot is a bit hard. It's like picking up an item directly in front of you, but no sound or items are picked up. I could get a screenshot from a recording when I go back to see it again. As a note, this happens randomly and very suddenly, so I may not get an image for a while. If I cannot find it, I will just assume it's not an issue in the game.
