Level editor crashed, and the recently opened map becomes empty.

[Rector]

I did save it at several times since I've been working on it for a couple of days. The strange matter is that I was moving a light object, and that caused the whole editor to crash (not a BlackBox, it stopped responding completly). It might just have been that the editor tried to (over)write something when I moved the object, and it froze and crashed.

I don't know, but from this, I don't see any other option than to begin all over with the map

Thanks for moving the thread to the right place. Was lazy not to search around for the exakt place to put it.
