[Amnesiaplayer]

I was working on my map.. cellar.. and i was busy for 4 hours!~!!
it was a Beautifull Map! everything was okay! and i saved the map more then 50 times -_- i click everytime on save if i place something lol...
and then i tested it everytime.. it was really good (there was scripting to!) and then i placed something (didn't saved) and my cousin accidently Turn off my pc ?
so i was restarting the pc... to finish my map... and my WHOLE map was gone... Cellar. map was but if i open the map file it is Clear ?! scripting file is always full... but my map is GONE ?! i worked 4 hours for nothing ?! do you got this problem to ?!
please tell me it is an bug and it can be fixed... i want that map back...
