JR Amtrak P42 window issue

[irondiamondrail]

hey all. for some reason the phase 5 amtrak p42 genesis from jointed rail has an issue with one of the rear windows. its see through when the rest are blacked off, you can see the ground on the other side of the engine through the window. none of the other p42 versions have this issue for some reason. has anyone else been experiencing this issue, if so how can i fix it?

The item was obsoleted by a new version from N3V. It appears the window block on the right side has its normals inverted, so you can see right through it.
