 It can happen that board and schematic become inconsistent without that being your fault (eagle sometimes just fails with no reason). The script [[mov.ulp]] helps you if you want to restore the placement and orientation of the parts. Rip all wires ('''RIP;''') and then run the script on the board. It will produce an output window, whose content you can either copy or save to a file. Do not execute this. Next you close eagle and delete the board file (*.brd).
