When I accidentally tried to load a TmxMap "lab" instead of its actual name "Lab", I got very misleading Error messages because the XML parser tried to parse the directory "lab" instead of the contained "Lab.tmx". Maybe we should include a mechanism to prevent this kind of misunderstanding and check for lowercased matches in the project Resources.
