Level 1070 solution is old and not the same options or order. I have tried so many times that I finally came here for solution and the video is not the same. The left column had an extra piece which is no longer there and seems to be the key to the reason I can't finish. I can't get the last purple as its trapped, and then the lighter purple (last option on left column) is not there anymore and so I can't open that section of the board.
