Blinky black/lit Lighting on objects

[Quiet_Bot]

So i'm working on a map of course (otherwise i wouldn't post here)

Simply put, my physboxes seem to have completely broken lighting. I noticed this every since i toned down the light_Enviroment to make the map completely dark.

Now These textures appear like

And at a slightly different camera angle show up as properly lit like

I've tried deleting every god-damn light on the boat. And I'm currently at a loss.

Error checker tells me the compile log has nothing. Besides a random broken brush (which i fixed) and some "zero area child patch" error a few times. I've had these errors for ages and i don't see exactly what changed to make the items look like this.

Any clues what could be causing it? i'm about to re-delete all the lights in my map.
