I noticed some awkward flashing when I was flying around in my space ship. I gave the same model to my buddy and he has the same issue I tried deleting all of the bricks and the issue still happened
Edit: The place file has sensitive information I will provide it to the admins if requested.
I’ve experienced the same problem before.
If an admin wants to check the place out, here. I somewhat narrowed it down for this post; there’s a part in workspace named “DeleteMe”, delete it and the bug vanishes for whatever reason.
A little bit of testing while typing this post up revealed that it seems to happen when DeleteMe is technically on-screen. Like you if make DeleteMe big enough to see so far away and clip your camera into the wall of the room, you can see the room becomes light when DeleteMe is visible and becomes properly lit when DeleteMe isn’t visible.
Hopefully Stravant can forward this to the client team 
I had this problem too and made a thread about it months ago.
