HALP! Render window # lights debug confusion

Posted this on another forum, but no luck, so copy/pasting here and hopefully I can find an answer...

 

Ok, so this problem has been plaguing me for days, and I keep coming back to it. I am so confused.

 

According to the Wiki, when you debug lights, a red area indicates too many lights hitting an object. So when I was debugging my mine, I saw this:

Now, the area looks like this without the debug on:

As you can see from the light radii, almost NOTHING is touching that piece! ???? This is what it looks like from the other side with my crazy attempt to room/portal the red out:

The two lights at the bottom of that picture are shadowcasters whose radii don't leave their little alcoves.

 

Anyhow, I took the red piece out (MineCLDoor04 I think it's called) and used Ctrl-F to make it a paper roll. Note that there was no info at all attached to that reference. Well, rather than sending the paper roll to the john, I just used Ctrl-F again and put it back in place. And this is what it looked like afterwards:

Eugh??? I used Ctrl-F twice - that's it. Still, almost zero lights are touching that piece and the purple fence-looking thing is actually a bridge high up that has a light at either end. All my lights are DefaultTorchNS_NoMove or DefaultCandleNS (the one to the right in the first pictures, and bottom right on the third), except the spotlight, which doesn't reach the area. I've reduced the brightness and radii on all my lights to next to nothing with no effect.

 

When testing, I'm getting great FPS through the whole mine - except when I look at that wall. Then it drops to the teens.

 

HALP????

 

 

Edit: Deleting that piece and dragging a new one to the screen from the object window makes no difference.
