Certain Sprites of the Wooden Gate are inaccurate to others. I.e. a left gate's sprites look different from those of a right gate's sprites at certain angles when placed next to one another, even though you'd expect them to look the same, just flipped. (The following are a bunch of screenshots of all the gate skins, opened and closed, at different camera angles and even a different orientation when built, 16 screenshots in total. I apologize for the wall of images, but I feel this should be shown thorough enough as I am not sure I am doing a good job explaining it.)
Place down two wooden gates side by side and notice a few discrepancies between the sprites of the left and right doors.
