Terrain deletion!

How can i stop my terrain from been constantly deleted???. I needed to configure a humanoid form for mechanim so to be safe (i thought)i I opened a new scene and did it in there then went back to load my old scene and the terrain was gone. I had 20 scene saves and every single one had no terrain how do u save terrain when u save a scene this is retarded.

Also why does configuring a bloody humanoid wipe a scene anyway? what does one have to do with the other its absurd.

Well thats just brilliant i had a empty sence cept for camera direct light and 1st person control saved scene to configure a humanoid and when i was done not only was the terrain not deleted i didn’t have to even load the scene it was still there. Hows about some bloody consistency Unity the amount of times something worked for me then without any change suddenly didn’t its crazy…
