Not a bug but MY WORK :O IT REFRESHED :C WHYYYYYY and thats what im asking you. When I was fixing my map in map editor FOR A WHILE....... :O REFRESHED all my work and the work didnt save. :C Please somebody tell me why!

What do you mean by refreshed? Refreshed as in when you refresh a page and when you got back, It wasn't saved?

No, I did'nt refresh the page but the Map editor ITSELF refreshed.
