An odd one. I found a xpack with a grandstand which fit the style of my WIP but it had no canopy cover. The grandstand does have the framework for a canopy however. So I tried to lay a wall flat and make it into a canopy. It is visible in BTB. When I export to GTR2 the grandstand is there but the wall canopy is gone. I go to run a race and the wall canopy is visible from the grid. I do a lap and it is gone... I do another lap and it is there... Very odd. Anyone have any idea why this may be happening or how to fix??
