I have made a very simple, box-shaped, BSP-based house, which all builds fine except for the attic. I know that you're only supposed to use very basic shapes when implementing BSP, and I have - the attic is a resized copy of another brush in the house with a subtraction brush to allow for a ladder to reach into it, and is basically just a thin box separating the top of the house from the other floors. However, when building geometry, the top face of this attic brush invariably disappears. Could anyone give me an idea on why this is occurring?

It's possibly a brush order problem. You can force order by selecting that add brush that gets subtracted, right click on it in the properties there somewhere you can change order. Do this on the wire frame, not shaded, otherwise you get surface properties. Or, kill that brush forming the floor and create a new one. -
Yeah thanks for the help man, I just created a new one and it's working now
