I need help getting maps made

[TheGreatCthulhu]

My map doesn't show up on my custom stories list

Make sure that the folder structure is correct (custom_stories/yourCustomStoryName/maps), that you have a well-formed custom_story_settings.cfg, and that the map file itself doesn't have an error of some sort (invalid entities and such). About this last bit: when you open a map in the level editor, the editor should show a message box if there are any such errors; if you simply resave, the new version will discard erroneous entities.
