Regular windows and reinforced windows look exactly the same

[Walrus]

The 3 windows that are to the bottom left of the window/grille set above my character are normal windows, while the 3 windows to the bottom right of the window/grille set are reinforced windows. They both share the sprite for the regular windows. Also, around half of the reinforced windows that are built into the map have the regular window sprite, which you can see in the left/right edges of the photo.
