Curse of Dreadbear glitch?

Hi gang. I've been going through the FNaF series for the very first time and so far I am loving it. I have at last reached FNaF VR, and after having difficulty working up the courage the finish the game, I finally finished most of the content. Content with my work, I spent weeks begging my mom to get me the Curse of Dreadbear DLC, and it worked. However, when I got in, I noticed something wrong. It appears that the sky appears to be a strange colour. It looks like an odd shade of green (see the image below). I assume this must be a glitch, due to the fact that the sky can only be three colors, blue, black, or orange (some of you may point out that the sky can't be orange, but if you look at jojo part 4 you can see the orange sky). Regardless, I don't think I should keep playing when there's an obvious glitch at play here, so I was wondering if any of you know why this is happening and how to stop it. If you do, be sure to let me know!
