An Invisible Brush

[MagSul]

Hi! I have about nine identical doorways and this is the only one with this issue. It's not duplicate brushes occupying the same space and the surface you're looking at isn't caulked or anything, it has a proper texture. Does anyone know why this thing keeps persisting?

I can't really think of a good reason for that door to be like that. It happens sometimes that structural brushes with manipulated vertexes have invisible faces; generally, turning them to detail brushes fixes the problem. Another solution could be to remake the door, or that specific part.

I've remade that specific part a few times. I've tried building it in a slightly different shape as well, but that surface always winds up with the same result. As mentioned above, it's just strange that it's only this door, when there are several others which're identical. Though if you say making the brush a detail may fix the problem, I'll try building something behind it so that I can convert it without the map leaking.

 

EDIT: Making the brush into a detail didn't resolve the issue.

Is there an area portal?

[MagSul]

There was, yes. I rebuilt the brush in question yet again today and for some reason it's working for now. If this problem reappears, I'll come right back!

Make sure all but one of the sides of the areaportal are system/skip
