Out of memory loading solid

This Hammer error usually occurs when loading invalid solid structures, but can occur in other ways as well. Until the solids are removed in a text editor, the map won't load in the editor.

Fixing

Open your map in your text editor of choice. Go to the line that Hammer specifies and delete the entire solid class that encases it. An example of a damaged solid is listed below.
