Summary of the bug : In the Industrial map, there is a rock that only has one visible side. Not a big deal, but it's there.
When does this happen : while racing
On which track did it happen : Industrial
How often does this happen : Always (It's a texture)
How to replicate the steps (if reproducible) : At the start of the race, take the left path, then the second left that takes you through the tunnel. Right as the tunnel begins, turn right and there should be a rock with a side that isn't there.
More details : This is the only one I have seen, but there might be more, so I'd double check everything if I could.
