Mount Equipment Resource and TGEA 1.81

I have tried using the mount equipment resource found here www.garagegames.com/community/resource/view/10304/ with TGEA 1.81. I have seen this problem with even a clean version of the engine. The problem is that vehicle wheels do not render with the resource installed. The are present and serve their purpose, they even render a shadow, but they are invisible.

I am hoping someone else has already figured out why. I tracked down the problem to the prepBatchRender function changes, but am still working out why.
