If you make double indentation instead of single while declaring Terrain CC won't report any errors or crash it just silently swallows all what's left after incorrect fragment. Example:
Code:
AddTerrain = SLTerrain
      PresetName = Attack05Terrain
      BitmapFile = ContentFile
         Path = UnmappedLands.rte/Scenes/Attack05Terrain.bmp
      WrapX = 0
      WrapY = 0
      ScrollRatio = Vector
         X = -1.0
         Y = -1.0
      BackgroundTexture = ContentFile
         Path = Base.rte/Scenes/Textures/DirtDark.bmp
      AddTerrainFrosting = TerrainFrosting
         TargetMaterial = Material
            CopyOf = Topsoil
         FrostingMaterial = Material
            CopyOf = Grass
         MinThickness = 5
         MaxThickness = 7
         InAirOnly = 1
      AddTerrainDebris = TerrainDebris
         CopyOf = Gold
      AddTerrainDebris = TerrainDebris
         CopyOf = Plants
      AddTerrainDebris = TerrainDebris
         CopyOf = Boulders
BlaBlaBla
Notice double indentation after AddTerrain = SLTerrain. In this code BlaBlaBla will never trigger any errors, and everything after this chunk will not be parsed. Debugged this for an hour so watch your steps guys!
