I seem to be having some problems running a map that I am testing. I have made sure there are no invalid structures and there are no leaks in the level (According to the ZHLT compiler). Yet my map refuses to function properly! Everytime I try to load it up, Half Life (Or in this case, Sven-Coop) crashes and I am prompted with a error message that says "Bad Surface Extents at blah blah blah".

I could really use some help with this issue.
