Ok, problem solved. LS Tools is working just fine. In order to correctly change your levels name (and avoid issues described above) you must open lsb files located in Globals folder using LS Tools. Next serch for line LevelName and correct it. The same goes with MapKey. You must modify one of the numbers located on the right (Value column). Save everything correctly, open your level and voilŕ mon ami. Inside the editor LevelName is displayed as GUID Identificator.

Edit
Did not work. This got fubar. LS Tools did not help. Time to put my super secret ambitious multi level project on the shelf.
