Map: bonkers image - Radiant Mapping

This is now bugging the heck out of me.
So I went in and deleted all the visible brushes by individual selection.
I clicked one at a time and zapped them.

Now if I edit the map as text:

// entity 0
{
"classname" "worldspawn"
"wad" "pkplus.wad;quake101.wad"
// brush 0

Brushes with planes radiant does NOT display.
How about that.

Might those be these warnings?
