Testing New Maps in Dev Environment

The game doesn't rely on the leveleditor.cfg file's existence or correctness to load up, only the level editor ever even considers that file (and if it doesn't exist, the level editor will create it). The HPL log will specify which configuration file it couldn't load/read. You said the log said main_settings.cfg, but it should be safe to delete that file, since the game should automatically create it.
