Hi, I did a PCB with 380 components from a schematic. Everything went fine. Then, I added additional components on the schematic and removed some. From the PCB, I do "Import Changes" and the changes went wrong. From the windows "Conform importing changes information", I see that **all** the "previous" component and the new ones are added and then the "previous" components are removed. I don't know if my explanations are clear but the consequence is the implementation of my components is removed. Please see picture below. I thank you by advance people that could help on this issue. Best regards. Christophe
