I think it means you have a BSP node with unbounded volume.

Try pressing Alt P and check for errors.

According to the coordinates, numerous brushes go beyond the edge of the grid.

Didn’t think they could, but i think some do. thanks

I moved all brushes away from the edge of the grid, and I checked for errors and it said there were none, and it still does it.
