Rocks'n'Diamonds

I'm not sure in which version did I find this bug, so it may be already fixed. When I create an empty levelgroup "Examples", it shows itself as a subdirectory inside it:
|- Examples
.....|- Examples
..........|- Examples
...............|- ...

I encountered this before, this is a infinite loop of the levelset folder
everytime you enter the levelset folder of forever infinite. (Found in the
empty JUE folder a long time ago, sorry I did'nt made a bug report of it)

This bug contains one folder and nothing else, expect the folder duplicates
in RND every you enter it if you know what I mean...
