Main Menu

Bad Surface Extents

I get the Error: 'Bad Surface Extents at ...' with numbers and a position after the error.

This error is usually caused by a problem with the map (game level) you are in.

It could be that the map itself has a design problem or that the map has become corrupted.

If this is a custom map, contact the author or download a newer version of the map.
