The long answer is: The Panzer IV H was one of our earliest CAD designs, as it was considered for Open Fire! Eventually, we settled on the StuG , and the Panzer IV H got put on the backburner. When we revisited the Panzer IV H, we upgraded it to include the Zimmerit, which became an unexpectedly demanding design task, perhaps distracting us from elements of the model that we’d assumed was already complete. How wrong we were!
Pattern recognition is a funny thing. The human brain has a fantastic capacity to see what it expects to see. Forty-odd Battlefront employees (not to mention tons of gamers!) looked at renders and rapid prototypes of the tank and not one rivet counter among us noticed.
