Thank you guys for your compassion... ;) the strange things is that the image I had is a mix of my WIP: The mountain material is the first I put on terrains (but I changed it 4 savings ago), camera setting was one of the first I had (changed 5-6 saving ago), all the textures and windows are gone (last save: 2 savings before) but there are the Brycemen (inserted like the windows 2-3 savings before). Sky settings comes really out of the blue, but the saved skies settings button are still there so I can recover the last settings (strange..) Other strange thing: there a 4 wood beams after the bridge, when I done those I copied the main beams of the near tower... than I rescaled that cubes in order to have the pillars of the bridge. After the strange incident, they returned to the first dimension settings but in the position they were after I moved and resized them.... strange strange.... Some report of U.F.O. sight in south Europe recently?
