sorry for the late response
the version is V19 Stable Hotfix 02/09/2013 Steam
i try the savegame from the download link, to see if something went wrong during the upload and it works for me...
I had an infinite hidden movement screen today:
i uploaded a savegame just one turn before the infinite hidden movement screen
